Fusion 360 for 3D Printing LESSON 10: Designing Working Nuts and Bolts that Fit Properly

[@danny12345]

I have run out of words to thank you for your kindness.

[@MindfulJourneyer2277]

You’re the man. I really appreciate the time you take to do these videos! You are one of the few creators who constantly puts out content that inspires me and I’m sure many others!

[@cbrombaugh]

It was great for Fusion 360 to provide this thread design feature. Without that feature I would not have any idea how to make a screw. Thanks for teaching us how to do this Paul!

[@cbrombaugh]

I AM LEGEND! My first try at this homework produced threads that looked like they had been chewed on by a silly cat. :) After I reduced the print speed from 60 mm/sec to 30 and print quality from .2 mm to .12, the bolt and nut are great. I don't know how each change affected the results, but the combination produced great results. Thanks for all your time and effort in producing these great classes, Paul

[@spiralni]

a new subscriber sir!! thank you so much.

[@daviebutao6306]

I am having as much fun as I'm taking these lessons,God bless you sir for sharing this knowledge.

[@paulmcwhorter]

So nice of you

[@zorabixun]

Paul, you are doing very important work, and what is additional plus plus .... it's your way of talking and explaining ... very big thank you 😊

[@paulmcwhorter]

So nice of you

[@jslyto]

I love the multitasking with the phone , Thanks for all the great videos God-bless

[@edSabio572]

Thanks Paul! I understood everything because I repeated a lot of your lessons. I am new to this. I will try to add the hex pattern.

[@MrCameronMoore]

Wow! I've been hanging out for this Lesson. I do really enjoy the river cam and your stories about what's happening in your area. Living in Australia we tend to only hear bad news out of Africa.

[@Joe-os2dd]

Very thankful for your knowledge and hard work towards helping others ! God bless you !

[@davidelhami3816]

Thank you Paul. This is a nice design to challenge what we have learned so far🙏

[@manosm1]

What a nice view. I enjoy your lesson...!

[@jessekloberdanz246]

Haha Paul you are awesome, you always make me laugh. Appreciate you. iPhone as a hammer and "smooth as silk" were pretty funny. Carry on sir.

[@stephenyambor1422]

I looked around for how to use features of this program. Its very easy to get overwhelmed. I constructed the hex shape on my own, but had to take a break trying to get the the nice edges.

[@johnlvcar09]

Very helpful. Thank you

[@paulmcwhorter]

Glad it was helpful!

[@andyprest]

Great lessons Paul 👌 as you've said it's a little harder too do when not watching you, enjoying the learning phase for sure 👍 thank you..... does the nile not have humongous 🐊 in it? I would not be swimming in there 😂 no chance!

[@drzwithcrow6075]

Got my bolt to work - kinda. For some reason the round wasn't very round. The seam down the internal thread proved a nuisance, but most of it rubbed away and I can get the nut mostly on. The printer treated the extrusion of the bolt head as a separate item to the bolt shaft, the result being an internal double wall that wasn't that pretty. I redid the design joining the bodies together as one which seems to have worked in the drawing - I haven't printed the modified unit yet. The thread seemed also seemed too tight too fit so I increased the pull-back a tiny amount. I also added chamfers to the internal and external threads like real nuts and bolts have that get the thread started easier. That was far harder than I thought it should be - fusion kept selecting bodies rather than surfaces or 14 surfaces instead of 4, etc. More work required there. I can't wait for the case to finish printing so I can try the modified bolt.

[@danielsaenz5570]

I AM LEGEND! Homework wasn't too hard (Partly because I remembered how you did it from the last Fusion tutorials ;)

[@JeffinTD]

Great video. I’d been using push/pull but this is a much more elegant method.

[@ThomasKranias]

i wish i had teachers like you at school or even at the univesity.

[@charlesbrewer6552]

I like your fix for the tight threads. When I ran into this some time ago I cheated, I just ran a tap and a die over the two threads and trimmed them slightly. I guess it helps if you have the right tap and die.

[@danh9002]

Thank you so much!!

[@itsmeintorrespain2714]

Thumbs up on our Homework videos wold be good. I've noticed that you normally forget/don't.

[@randymc61]

Great video, thanks. But where is the lead-in for the thread? There should've been a chamfer on both sides of the nut, and on the end of the bolt. But the most important thing is, where is that island? Lol

[@keithlohmeyer]

I agree with the chamfers. Paul does not tell you where he lives but after watching enough of his videos he has dropped enough clues for me to find his compound on Google Earth.

[@codecage9333]

I put a chamfer on the threads but it seems to have messed with the threads enough that I had a little cleanup to do before I could thread the nut onto the bolt. I added the chamfer after making the threads, so wonder if I did the chamfer first then added the threads would it have made a difference?

[@darrenmccormick5152]

Nice lesson thanks

[@panicartist6033]

Great video. I did have filiment across the nut thread I will try printing it again later in 0.16 dynamic

[@paulmcwhorter]

I find dynamic quality works great for this.

[@jorgenonell1108]

Another great lesson Paul, thank you!

[@hammadshams]

Two things, 1 - thanks for a wonderful video again. 2- What 3 D printer you are using (or what 3d printer would you suggest for experimental jobs like the one you have created)

[@paulmcwhorter]

Look in the description, there is a link. I am using the Creality Ender 3 V2

[@sparkyrevenge]

Another great video!!

[@paulmcwhorter]

Glad you like them!

[@fjdelahoz]

Thanks!

[@mikaelkalarne334]

It took three hours figuring out the rounded ridge.

[@anurajms]

thank you

[@unamazedtheist9136]

let's print dis nuts!

[@kamaumaina2000]

helping with the youtube juice

[@warrenscorner]

Helping out the KZbin juice. You made that look so easy! I still don’t have a printer. The hobby room is making good progress. The suspended ceiling is almost complete. I’ve asked this question before. What about the fumes from the printer? The last answer someone gave me was not to worry about it but you’ve mentioned before that the fumes bothered you. I’m thinking I should put in an exhaust fan. I will be doing some soldering as well.

[@paulmcwhorter]

Ventillation would be nice if you can manage it.

[@codecage9333]

@Warren's Corner... As Paul says ventilation would be nice, but maybe not 100% needed. I've been soldering for over 50 years and never felt the need for ventilation for that anyway. I've only 3D printed for a couple of years and only with PLA and PETG. I've yet to notice any obnoxious fumes. By the way I don't have any lung or breathing issues even after all this time. I do have an enclosure on order for my printer just in case I decide to print any ABS or PC blend. But that is more for the benefit of a higher temperature print environment for those filaments. Plus I guess the enclosure may keep dust and "silly cat" hair from accumulating on the printer itself.

[@dale_ch]

Very interesting Paul 👍👍

[@scottwait3585]

Awesome! Thanks Paul

[@larryplatzek9017]

As usual a GREAT LESSON!

[@paulmcwhorter]

Glad you liked it!

[@onecarwood]

Thanks for the video. I was st I created exactly as you but the bolt is still to tight. Will try to do the same to the nut and print.

[@MrCameronMoore]

Well I've finally managed to print Paul's example in this Lesson. Here's my list of issues Issue 1 - the bolt and hole in the nut were slightly elliptical, solution tighten the belts on the X and Y axes. Issue 2- the thread in the nut had cords of filament cutting across the hole (not stringing), solution print at a higher resolution i.e. set slicing to "Dynamic Quality - 0.16mm. Issue 3 - The nut kept coming unstuck from the bed, solution level the bed to a higher precision, i.e. when using a sheet of paper to align the bed go for a higher level of friction of the paper between the printer nozzle and bed. Now to do the homework.

[@paulmcwhorter]

Welcome to life with a 3D printer. Definitely requires patience and tweaking but hopefully the reward of getting working makes it worth while.

[@jamieyz]

Enjoying the lessons. Do you know island boy and girl?

[@anwarzebkhan]

How do you knock the print on i phone 13 . The phone is worth of may be five 3d printers + nuts and bolts.

[@danielsaenz5570]

Great video! Instead of going to the hardware store to get some Nuts and bolts just go to the 3D printer (And wait half the day for it to print ;)

[@avgjoeshow4208]

What island is that behind you? what country is it in? are they like a more primitive native or just do farming and fishing there because of the space and fish population?

[@andrewcourt5156]

Hi Paul.. love the video series…. Does the “little” adjustment you have to make to the bolt thread make it “non standard” and incompatible with a nut, with the same thread spec, but just purchased from a hardware store. e.g. for any particular application do you have to print both the nut and bolt?

[@jobinp]

Hi Paul, Here is my solution to the assignment: • My work in Fusion 360: kzbin.info/www/bejne/fJDLmamEgqunY5Y • Bolt and nut once printed: kzbin.info/www/bejne/pYTMl6ubf9h6iKs Thanks for your great lessons!

[@paulmcwhorter]

Nice work!

[@rickbonari4493]

I was able to print out the nut and bolt, they printed out really well except for one thing. The nut and bolt threads printed very well except for one area where there was a bumped up ridge on the threads in one small area going up and down vertically on the threads. I'm wondering what this could be caused by? My first thought was a retraction issue with the printer? When you sliced the nut and bolt in Cura did you modify any of the settings? Also wondering if anyone else has had this issue?

[@skydragon1966]

This is awesome

[@alistaircook1997]

Hi Paul, great content, is there a way in Fusion 360 to make a screw head ?. I can make a bolt with a slot across or an allen key hole using the polygon , but what about phillips/pozidriv type head.

[@anwarzebkhan]

thank you sir.

[@chrisarmstrong8198]

Maybe adjusting the "Class" variable in the thread dialogue box would adjust the clearance automatically ?

[@keithlohmeyer]

Yes setting the class to 1A does make it a little looser but not really enough. I also believe it only affects the groove depth and not the outer diameter. Paul's mod reduces the outer diameter as well

[@curtismartin252]

How do you find the live stream on his island background???

[@paulmcwhorter]

Maybe I dont understand the question, but the river is really behind me. You are seeing what it actually there.

[@codecage9333]

Here is a link to my Homework solution to Lesson 10: kzbin.info/www/bejne/pXeZn3yYZtGLZs0 Hope it isn't too painful to watch! 🤠

[@paulmcwhorter]

Nice Work.

[@rickbonari4493]

Is it best to print with the best quality or standard quality in Cura Slicer?

[@paulmcwhorter]

I use dynamic quality usually. In general the higher the quality the slower the print.

[@rickbonari4493]

How did you get the threads to print correctly? Threads print ok except that area where the seam and blobs are. Are there any cura settings that need to be changed?

[@danny12345]

Hi, what material do you suggest to clean the print surface?

[@paulmcwhorter]

People suggest isopropyl alcohol. I use a little soapy water and rinse well, and dry with a lint free cloth. That works for me.

[@danny12345]

@@paulmcwhorter Thank you

Thank you. Can one determine if a sketch is constrained by lines. If blue, not constrained, if black, constrated. Also, there is no such thing as a silly cat video.
