3D Printing & Using NASA Space Wrench Here on Earth - @Barnacules

Did you know I've made over 800+ other videos on KZbin? Hit that SUBSCRIBE button and watch another Barnacules Nerdgasm video right after this one! 🍿 I 3D print the wrench designed for the ISS commander Barry Wilmore (AKA. Butch) designed by Made In Space & NASA. This is the first tool 3D printed in space! I use both PLA and colorFabb XT Materials to test there strengths and weaknesses and I was really surprised!

ColorFabb XT filament is produced from Amphora 3D™ Polymer by Eastman Chemical Company.
Clear amorphous copolyester filament for 3D Printers
Effective Diameter
1.75 mm +/- 0.05 mm
2.85mm+/- 0.05 (will work with any 3mm printer, but awesome for Bowden printers such as Ultimaker)
1 Spool contains min. 750 grams of filament
Processing temperature = 230 - 260 degrees C
Please read this:
Switching back to PLA or another material is usually done by ‘purging’ the hot-end of _XT material. Heating up the hot-end to 240 C and feeding through new material will purge the hotend of _XT. Another method would be to insert filament manually in the hotend (while hot) and retracting it immediately. _XT will stick to the end of the filament which can then be cut off. Repeat this several times to completely clean out the hot-end. Ensure hot end is completely purged prior to starting prints with the new material.
And what is ColorFabb_XT
The ColorFabb_XT range is a special amorphous copolyester with a Tg of 75 C. So you can use this up to 70 degrees C. Toughness is high. Elongation at break = 50% (yield). In comparison, the normal PLA / PHA range has a elongation of approx 10% at yield, but has very good layer adhesion properties and is a bit softer compared to PLA. Both qualities have minimum warping tendencies.
In addition to this, ColorFabb XT is very transparent and odourless compared to ABS.

Questions & Answers
Q) Why didn't you print it in Bronzefill?
A) The bronze filament is bronze dust held together with PLA so it's actually weaker then PLA by itself so it would have been pointless. Email business inquiries to [e-mail] Help the channel by donating BitCoin to 1MfVZVMjfUUq8srg1d4RbgXR5e7JLw7R6P

[@Lvvcassss]

You should totally test the wrench against a torque meter...or just against a torque wrench and see if it actually delivers the torque mentioned on the handle :)

[@ColtonBlumhagen]

They should design a 2nd wrench for loosening, then you'd just have a different one for each. Way easier than a selector switch. *Edit* LOL You literally just said that in the video

[@Barnacules]

Great minds think alike :D

[@GeoDelGonzo]

Can't you just mirror the model and make the loosening ratchet? :/

[@ColtonBlumhagen]

GeoDelGonzo Yes that's what Jerry said.

[@GeoDelGonzo]

GeoDelGonzo ahhh yeah... Just got to that part. I'll shut up now :P Sorry!

[@will3346]

Yes it would be better but they have limited abs plastic up there so they have to conserve it

[@complicated_AK74]

The thing that goes between the teeth that grips the gear there should be 4 of them 1 on each corner so it can distribute the load on more then one teeth so it wont wear down as much.

[@Barnacules]

That is a great idea, they should re-design a new version of it with that upgrade to increase the torque.

[@MiChAeLoKGB]

Barnacules Nerdgasm Well, send that to NASA Barnacules Nerdgasm Maybe youll get some "USA Nerd medal" xD

[@fireninjabeast183]

Barnacules Nerdgasm www.thingiverse.com/thing:618822/#comments Doctor Who Iphone 6 Case - Embossed image of Tardis and Doctor this is for your iphone 6 i foned can you use fuxe pla or lbs

[@lancegreene426]

actually you know how barnacules mentioned mirroring it and printing another wrench? well you can just mirror the clutchimg mechanism and the square knob of the wrench onto the back of the wrench itself, so one side can tighten, then flip it and the otehr side will loosen. I've seen it on youmagine or thingiverse somewhere

[@newolku]

Lance Greene Great idea

[@trendingnewsandstuff]

Great down to earth explanation about how 3D Printing works. Very easy to understand.

[@TheTubeTempest]

The wrench is supposed to slip when you twist to hard so it will not strip the bolts.

[@digmatology]

No ratchet dont slop until they break buy one and test it

[@tahlermohz]

Hey! I've been watching your channel since around the time you were laid off of your work and honestly, you're one of my favorite channels. Everytime I see your video in my sub box I get really excited. Keep up the good work, it's been amazing seeing you grow. And your videos are amazing, keep up the amazing work!

[@Barnacules]

Thank you!

[@unknownVS13]

I wish you had tried the bronze PLA as well

[@Barnacules]

It would have been pointless, the Bronze PLA is actually weaker then regular PLA. It would have looked badass though as a display piece.

[@KaltatheNobleMind]

he should have! figure it would be very strong and durible.

[@Barnacules]

Meir Teichman Nope, the bronze dust is held together with PLA so it's actually more brittle and weaker then regular PLA.

[@KaltatheNobleMind]

Barnacules Nerdgasm ah! completley forgot about that structureXD you have doen eveyrhting right:D o wodner if there is a process that removes the PLA and leaves only the metal dust,like soem sort of lost wax mold tingie. bet it will shrink considerably though and easier to just print a wax model to do lost wax casting or just use those expensive metal printers.

[@stevenmcelroy8099]

Barnacules Nerdgasm Try wood

[@dpmakestuff]

I just wanted to take a minute to tell you how much I admire what you have created. After the last Barnavlog I left a comment. I mentioned that I had a small channel of my own and after posting that, I had so many of your subscribers come over to my channel and say wonderful things to me. You've built a beautiful place here. I hope you don't plan on leaving anytime soon. Thanks!

[@croc1608]

if you just print a 3/8 " nob on the other side you can use it to loosen things as well.

[@brandon9271]

exactly! :)

[@DnBastard]

beat me to it! surprised they didn't do this originally

[@crunch9876]

And how much harder will that be to print? Sounds like a lot of support material to me

[@umuahjokuamadi-obi7452]

+crunch9876 oh yeah :/

[@Stinky_boyy]

I love how you fade out the video when the printing is almost done. I dont know why I like it so much. It just gives it a really professional and cool effect. Thanks for the amazing videos and please keep up the good work

[@MangaMiyn]

OR YOU CAN HAVE ONE RATCHET WITH 2 ENDS

[@3dpprofessor]

I don't think your PLA wrench was wearing out the teeth. If you look closely there's a little arm pushing the ratchety part back. I'm going to have a video taking a closer look at it but that spring actually takes advantage of slicer errors to make a flexible arm that in ABS will push the arm back, but in PLA will probably break after a few uses. If you took your PLA wrench apart I'll bet you'll find that the little spring arm is actually the part that broke, not the teeth wearing out. I may be wrong, but that's my guess.

[@Popshockercrx]

All that needs to be done to use same wrench to loosen without a selector is print a socket square on the other side and one side tightens and the other loosens and m sure theyll need to figure out support and bridging when its being printed

[@Barnacules]

Exactly! Just like my little wrench. I might modify the design to do this.

[@sashablfc]

Or just have a hole there, print the rectangle separate and then you slide the rectangle though which ever way you want it. (they do this for real wrenches currently too)

[@LawrenceTimme]

Barnacules Nerdgasm why do you sound wierd in this video? you change to a cheaper mic?

[@obamacare3225]

Congrats on 300k! You deserve every bit of it! You have inspired me to do KZbin, and I am 14 years old! You are awesome man and keep up the great work!

[@AnyGameHD]

Jerry, don't think of your fat as fat. Do what my dad does and thing of it as power. You're a very powerful person

[@Barnacules]

[@lilturk726]

DC_DANNY_DC I just consider Jerry as "festively plump"

[@neodan2004]

Great design. For the wrench to move backwords you could extend the bolt shaft in the other direction, the wrench would have 2 bolts, one on each face, one side for tightening and the other side for loosening the screw, like mirroring.

[@lemonsipper1199]

Hey Jerry! Love your videos, especially these 3D printing ones.

[@psp7677]

I really like how you actaully put links in your discription rather than what most YT'ers do they just copy and paste the SAME THING in every video.

[@mcs11234]

You should try 3d printing some keycaps out of your keyboard from various materials. Great vid btw!

[@itlbok333]

Well, late to the game but printing this now. Great video! The fast speak kills me every time! Nice work Barnacle Guy... BTW, you were the only one that had the print specifics... helped mucho!

[@TheAxio300]

you could always put a square nub on both sides of the ratchet ie one side to tighten, one side to loosen

[@dtriplett03]

+TheAxio300 BINGO!)))

[@bluze6131]

You have the best sense of humor. I love how you can make fun of yourself and not be offended. By the way, I don’t want to come off as rude while saying this, but this makes me happier that a lot of humans are amazingly hearted.

[@chemicalvamp]

Im pretty sure You can invert the wrench by scaling it in negative in the X axis in Cura!

[@stevenkistler5063]

Definitely think that you are going in the right direction with these 3D printer videos. With the newer 3D printing stuff coming out, I think you are implementing them well and using them in your videos to really produce awesome content. Good job, Jerry

[@lmaoroflcopter]

Is the 3in-lb a torque wrench rating. E.g. When the wrench started slipping doing up the bolt then you had reached the set torque of 3in-lb. That's even more awesome as essentially the made in space guys would have made it from the tolerances of the ABS. Designing something to fail (in a controlled reusable manner) at a particular torque using 3d printing... Awesome.

[@xoat4997]

I was going to ask why did they design it to ratchet? Was it really needed? It would have better to make a non-ratcheting breaker bar. They could have used the breaker bar as one wrench for tightening and loosening. Also, the wrench could have a higher torque spec that way. Your explanation is probably the reason they designed it that way. They wanted a torque wrench instead.

[@Mushnp]

xOAT Or because they wanted something that works in a much smaller space. With a breaker bar you either have to make a larger rotation or continually removing and readjusting your position.

[@sashablfc]

No, just like food expiration dates are not dead set; you won't die if you eat it 20 seconds after the expiration date however the chances of the food bad after said date is very high.

[@ZeldagigafanMatthew]

Inch-pound is a torque rating, much in the same way as the Newton-Meter, and while it would have a higher torque capability if it was not a ratchet design, that actually makes it harder to use in general. Instead of just ratcheting the wrench back, you have to take the wrench the off, put it back in a position that you can work with, put it back on, turn it, and repeat. No tool is more useful than the ratchet wrench, since you only need to take it off only once during the installation/removal process.

[@rich1051414]

The ratcheting is useful for the awkwardness of space/0 g's. It is probably exponentially more useful than being on the ground.

[@rilufuzz]

I've been subbed for a while now, and i have to say your varied content really keeps me watching. Any thing from games to 3-d printing. Your channel is a great way to waste some time :) keep it up man!

[@johnparks6936]

I wish you'd do a video on 3d printed keycaps! That would be awesome.

[@karlabrgamer]

I love your 3D printing videos! It's amazing to see what things we can print on these things! Besides, your videos are unique, I love watching them. Keep it up! :)

[@JeffryLandry]

If they can print a functional tool in space, how long will it be before they are able to print out the space station itself?

[@Barnacules]

Just a matter of time! That would be pretty awesome.

[@JoeyPlaysGamess]

For all we know, in another dimension, they may have already done that.

[@newtracetriad]

Barnacules Nerdgasm Just send spools of material into space and the station just keeps getting bigger? sounds good

[@astcomjakecw]

They already can Gimp, even conductive panels. We cant print in metal up there but there are other, lighter ways with a large reprap. We can even print fully functional solar panels. soon will print circuits with the new conductive filaments.

[@JeffryLandry]

Pretty soon the only jobs that aren’t obsolete will be programming the computers to do new things.

[@mcarbunaru]

Hi. Just saw the video now. You don't need to make the second racket for loosening. You just need to mirror the square thing where you put the extension to the other side of the tool so for each side you have a different direction of movement.

[@mattv2099]

that was awesome!

"I'm holding the shaft really tight" -Jerry

[@sciwolf359]

You know that is pretty darn cool!! Printing toys and models is fun but this, making a very practical usable tool is showing the beginnings of the real practical uses of these 3-D printers.

[@zdrux]

You know sucks? The fact that in a 100 years, we'll be able to buy a new console online and have it printed at home in a few minutes. No wasted materials for packaging, no delivery time, and can be repaired with parts printed from tech support... and none of us will be around to experience it :(

[@Barnacules]

Maybe they will perfect cloning by then and we can just keep recycling into fresh new bodies.

[@maximiliankern7503]

Barnacules Nerdgasm that would be awesome or anti aging pills

[@ddha0000]

pretty sure consoles wont be around by then

[@TheChrisglasgow]

In 10 years they'll prob be no consoles as such, 100 years we prob wont even be gaming like we do today it will be more like having our own holodeck.

[@azdeh1894]

TheChrisglasgow I wonder which is more feasible though..a holodeck or just having some kind of chip in your head to go "online". Good bye to schools..man that's kinda sad lol would be even more anti-social than we are now. Rant finished.

[@HunterDigsMinecraft]

"And I'm holding the shaft reaky tight", hahaha good work jerry

[@Fdsagio]

Print a 3D printer with a printer. Then print 2 more with the 2 you have. Then print 4 with the four you have. Then print 8 with the 8 you have. Then rpint 16 with the 16 you have. Profit?

[@Fdsagio]

Yeah I know ;) it was supposed to be a joke.

[@xpuregamez923]

Fdsagio nah its a good idea in fact there is a website that does that it could be good revenue

[@CamaroRick]

you could put the 1/4" drive on the reverse side as well as the normal side, one wrench that will tighten and un-tighten depending on what side you use

[@DanielRut]

I'm watching this on the models 2 year anniversary of public release

[@xenonram]

Dan R I'm a year later!

[@DylanBenkeryodelelayheho]

[@TheKyshu]

I bet I'm not the only one, but I just have to say you are one of the few KZbinrs that genuinely and honestly feel like they are having fun doing their job, and that make me smile with each video. Keep on going, Jerry! :)

[@specificocean9490]

why didnt they just make a normal wrench that didnt ratchet? it could both loosen and tighten bolts without printing another tool, or even changing tools...

[@specificocean9490]

Ok, that's a good reason for this style of wrench, however I think a completely solid one with no gear or ratchet would still be more useful.as you wouldn't have to worry about the gear slipping and you could use it to both loosen and tighten bolts.

[@DahTreeSniffer]

+Jebediah Kerman you can switch directions on a ratchet..

[@specificocean9490]

not on this one, he said you have to mirror the 3d model and reprint to get a wrench that will ratchet in the other direction. Also, even if this ratchet did switch, there would still be the issue with the gear slipping.

[@ReSummit]

That's easy to do with Sketchup.

[@specificocean9490]

Danny Vu its not about how easy it its to model the flipped version, its about how long it takes to physically print. Not only would you have to print 2 different wrenches to tighten and loosen bolts, the gear would still break and make it a useless hunk of plastic. Hands down it would be easier to just make it without the gear and fill in the area where the gear was with plastic.

[@MultiSanderrr]

I love the bit more technical 3d printed stuff like this and the planetary gears. Please do more of them :)

[@Martin-vh3ei]

They use inches and pounds in space? I thought science guys would use meters celsius and kilogram..

[@sashablfc]

Kelvin.

[@cesrai]

They use the SI system I guess.

[@skylercox939]

They can probably do conversions well enough in their heads so wouldn't matter much.

[@DMoney0527]

Would to see a showcase of all your past 3D prints and do's/don'ts of 3D printing

[@justinnitsuj7041]

cringed each time that ratchet was called a wrench

[@Logic44]

The ratchet is the mechanism _IN_ the wrench, though. So it technically is a wrench, that's why the technical term is "Socket *Wrench* "

[@MattPixInc]

I think it's awesome that you respond to people on here Jerry! Great video as always

[@caydongravens5825]

so for PLA what you need to do is shove a bunch of squishy material like silicon on the left side of the little arm, it gets rid of the wobble and the loss of traction issue. I find that the internal "spring" on that little arm isnt enough for PLA and after a little bit of use it wears out. Ive been using my ratchet for about a week now on different things around the house and its holding up quite well.

[@tricksforedits7179]

that was one of the coolest wrenches I've ever seen.

[@nicosenpai5066]

Hey Jerry, I love your videos man. I just want to say that keep up the good work and don't worry (I know it's been a while now) about not having a job anymore because we will always be here to support you! :D

[@nils1953]

Love your videos. Waited so long to see another 3d print :D I love it :)

[@viktorfoggo5692]

I love your 3D printing videos man! I just subbed! And now demand MOAR!!!!

[@robodude666]

Very cool! Barnacules Nerdgasm would love to see a follow-up video comparing it to a torque wrench to see how it actually preformed. That didn't look like just 3 ft-lb!

[@KSPilo]

Barnacules Nerdgasm And now there are still people out there who think that you can't do usefull stuff with affordable 3D-Printers, just little figurines of manga and game characters und stuff like that. The ratchet wrench you printed was remarkable and I never had thought you could actually print it as one piece in one go. Learnd a lot again. Thanks Jerry.

[@PrintTech-3D]

The reason it doesn't have a selector switch and also why it slips when you tighten the bolt is because its a 3 inch pound TORQUE WRENCH and not a RATCHETING WRENCH hence the big 3 inch lb. printed on it. A torque wrench usually just tightens and its supposed to either slip or make a clicking noise when the desired torque is reached. It also didn't make sense to me why they wouldn't have a ratchet in the first place being that its a common tool but a 3 inch lb. Torque wrench is alot more specialized.

[@Barnacules]

I have two torque wrenches that have a selected switch for direction. Sometimes you want to measure breaking torque too.

[@PrintTech-3D]

Barnacules Nerdgasm that's true, it just wasnt mentioned in the video that it was a torque wrench. I love all you videos though, i wasnt trying to hate.

[@SusramRahul]

Printing a functional tool is just mind boggling. Ad being able to work with it is damn remarkable...

[@johnnywhip10]

I printed one of these a few days ago and had no Idea why it didn't work... Its probably because I printed it in PLA so I'm gonna go 3d print it in ABS now! Thanks for the help!

[@LiquidSquidYT]

Thnx for brining out the videos like every day dude! i really like that.

[@RetiredMegatron]

I love what you're doing man! Your channel is really entertaining.

[@DevilbyMoonlight]

just cut a square in the centre of the model before printing and use a square peg that way you can flip the rachet around to use it in the other direction

[@JacobStar91041]

Say I have no life or not, but everyday I check like 8 times for a new Barnacules video. It's exciting to see a new video by Jerry!

[@mii3000]

if you extent the part that you put the sockets on through the back of the wrench you can just flip it over to get the opposite direction of ratcheting. the only down side is that it will need support material to lift it off of the print surface to make room

[@TheHellHall]

Good stuff Jerry. And LOL I loved that quick pict of you as "Dental X-wing Pilot!" :D

[@BWAG26]

Glad I found your channel! You're funny, and your videos are high quality! I came across you while looking for reviews on the Elgato HD, which I just ordered 10 minutes ago. I'll be starting a Let's Play channel Monday!

[@arbhall7572]

I know this is a strange request Jerry, but here goes. Could you perhaps print a spice rack with a turn style? When I get my printer, thats one of the first things im going to print and was wondering if you could print one so we can all see the ins and outs of a build this size. If you would like to awesome, if not oh well, never hurts to ask. Have a good one man, and happy new year. I really love your content.

[@UncLester]

You should try to connect the printed wrench to a torque wrench. That way you can get some real numbers on how much force you can exert on the wrench using different printing materials.

[@bloodaid]

I just realized that you don't even need to mirror the model. You can just add another bolt-head-extrusion on the other side of the gear. Then label each side of the wrench with either "loosen" or "tighten"

[@DepecheMol]

Awesome video man, love the quality and the effort you put on this! Keep rocking

[@WaybackTECH]

Barnacules Nerdgasm Just print the 3/8" square end of the ratchet on both sides, then just flip it around in the socket or extension :) Also add a little "nub" to the square end to lock the socket/extension into like the real ones have. Now you need to make a wrench also Jerry and maybe some sockets as well. Plastic wrench or ratchet would be great for batteries as there would be no risk of shorting the positive of the battery to anything metal when taking it off. Cause we all know everyone remembers to take the negative side off first :) Take care Jerry!

[@folkswithnoface3887]

Great video Barnacules! And great little 3d model! post others objects!!

[@mitchellbaker2086]

Barnacules just put the part that the has the pieces for the socket part on both sides and it will turn a different way to tighten or loosen depending on which way you use it.

[@LacrosseFever18]

Can you do a strength test on all of the different materials and good uses for them?

[@ValTek_Armory]

I'm loving the new camera, man!

[@mylaptopdiednooo]

You should try printing the reverse model and printing a socket set to go along with it too and see how they hold up

[@Barnacules]

Ooooohhhh... 3D printed sockets. That would be pretty cool. Plus I could give it to my son Xander to play with.

[@troyrantanen]

Barnacules Nerdgasm No time to reply start printing

[@mylaptopdiednooo]

Barnacules Nerdgasm 3D print the sockets and like a toy/model to put together with see how well it can make bolts and nuts and the likes!

[@sienile]

The PLA wrench likely would be rated between 1 - 1.5 inch/pounds. That's not even enough torque to tighten a wall plate. Not that 3 in/lb is much better, but your ABS wrench seems to far exceed its rating. Could you check it against a torque wrench? (Couple the drives and turn the torque wrench until the rachet slips. Last torque held before the slip is the maximum effective torque.)

[@GamerV11]

To do a un-thightening just flip the wrench mechanism, delete the little arm for the extensor/reducer/socket, and put it on the other side, and BOOM there you go, also, for better "not snapping" just add a little half-ball on each side of the arm :D

[@corneliusfedorus254]

Although i find 3D printing fascinating, these videos aren't my thing. I still watch em because it's you, Jerbear.

[@Tom2112Tom]

They should have put a stud (the part where you connect the socket) on BOTH faces of the wrench. That way, just put your socket on the other side to loosen. And it's all contained in one wrench!

[@crazy-4-cooking]

Barnacules Nerdgasm I just found this Video, I know it is way to late, but as a former industrial mechanic I just had some ideas coming up while watching. 1) Why not Support the gear from more than one side so it can ersist more force? Try out with 3 and 4 for trangular and axial force resistance. 2) It would be very easy to make the tool 2-directional. There are wrenches, where you can Pop in the tool holder on the one side, so it Pops out on the other side. Now just add a + and a - (or R + L) on the tips of the tool holder and there you go. 3) The wrench does slip on the extentions and Tools you connect to. Bad thin in open space. Why not seperate the model in 2 phases (not parts) adding a hole in the tool holder. When the Printer stops you just put a Piece of iron (magnets are polarized) in that whole and after the Printer continues completing the model. 4) You could print hte extentions and sockets too, there I would recomment doing like in 3) 2 phases or popping a small Neodym magnet in so they bond good together and do not get lost. 4) The wrech should have a Little hole on the end for a wrist strap, just think about wiimotes. Or better have a cord with an bajonet lock which plugs into a socket on a bracelet. (open space usage). 5) Ever thought about a magnetic wrist holder for extentions and sockets? (looking towards the magnetic bits at 4) ) It would be cool to get your Feedback on this as it is just theory and might simply not work practical. Thanks for the awesome chanel it really rocks in many ways, Keep it up.

[@wadesta1986]

Keep the videos coming Jerry. Your a top person and I love watching your videos!

put a indent on the back side of the wrench, then print a small adapter to fit the indent. when you want to loosen something, use the other side.

[@GeorgeKartali]

Extreamlly cool they could design it with a shaft going out on both sides then it would not matter you would only need one rench but could put ratchet on what ever side you need for tighten and loosen.

Excellent video. I find this video lenght around 10-15 min is perfect!

[@VincenzoSims]

Wow, this is pretty awesome, Barnacules Nerdgasm! :)

[@Gumey1]

I love this channel, It has to be one of my favorite ones! Keep making videos

[@11danzizzle11]

Awesome video, I love seeing all in one prints like this with moving parts! You should print the reducers, and see how strong those are, that would be nifty! (I know it wouldnt be that strong but would be cool)

[@tbtbtaylour]

I really admire you, Barnacules, for your bravery, and your attitude! Honestly, I don't know how you could make jokes about your weight, when I hate it when I do the same thing about my self.

[@gunsngeeks]

You could print this to work with "pass-through" sockets that way you could just flip to loosen. You could even go nuts and print a set of ratcheting open-end wrenches by replacing the socket stem with a sized hexagonal hole...

You said, "So I have to 'stay' that stuff like this just fascinates me, guys" @10:54.

[@MattWells0]

If you put the thing that the socket sits on on both sides of the wrench you could put the extender on one side to undo and on the other side to tighten.

[@victorbart]

Is it possible to print one with 1/2inch outputs on both sides? So you don't need to print both. Or what is also cool print one with a hexacon hole so you can use it also both ways on bolts. M8 size is nice to make.

[@gingernuttah]

You wouldn't actually need to print a second wrench to undo your nuts and bolts, just simply print another square head on the back of that wrench so side on it looked like a T shape. One side tightens, one side loosens, simple. The only disadvantage is it would be the head of the tool wouldn't be able to fit in quite as tight spaces, but this would be minimal.

thank you for the very informative video and experiment, I never realised you could just download the cad file from NASA's website, and that this wrench was a proper ratchet wrench with moving gear, very cool indeed

[@haptic9489]

I've been watching your videos for a long time keep putting out the best videos you da best !

[@johnnydoe6325]

Love your vids man,3D printing is always interesting,and I'm always amazed what can be done with the current consumer models.

[@bacawaka2813]

You could mirror the other version on the other end of the handle. Instead of having 2 you can have an all in one. It could save on materials and time.

[@lionhardt75]

That's a great idea!

[@spicydeath82]

Barnacules Nerdgasm After watching this I had the thought that you could modify the model to where the square shaft is longer and separate, and where it would be on the wrench you make it a square hole all the way through. that way you can use it for both operations.

[@yoshihd3832]

Congrats on hitting 300,000 subs!!!!!

[@meamjustme]

Instead of printing another wrench for loosening something, you could make the square adapter come out from both ends of the wrench. So you can select the function by placing the bit on one side or the other.

[@Barnacules]

The only problem would be all the support material you would need to print to make it work. It needs to print flat to be really efficient. But that being said it is possible and might be worth trying.

[@BenBradford1]

A ratcheting wrench is a luxury in that scenario really all you need is a solid breaker bar printed out
