As an American who has dealt with imperial hardware for the last 12 years of my career, I don't recommend that anyone uses imperial hardware or measurements for 3D printing because EVERYTHING in the slicer is done in mm. Metric is SO much easier to measure, model, modify, and print with. you get WAY cleaner and more accurate prints by using factors of the layer height and line widths.

[@kylek29]

Related side tip .. you can use Slicer modifiers to add additional walls around holes so that if a hole is slightly too small you can drill it out without compromising the part. The nut cut out with parallel lines is also in OrcaSlicer now as a sacrificial layer/bridge. With that said, software like Fusion 360 has access to large libraries of fasteners (e.g. McMaster Carr), so once you're comfortable modeling you can import the hardware and assemble, helps to find tolerance issues before you waste filament.

@@LiqdPT Oh true, liquid measures can be "fun" due to this. Canada used Imperial gallons before (mostly) going metric, which are 160 fl oz vs the US Gallon which is 128 fl oz. I'd remembered hearing that the difference was rooted in the British and the USA adopting a wine and beer gallon each. I can't remember which adopted which system. This very difference has lead to many arguments over volume amounts with my parents, and older generations. They assume that everything they see measured in gallons here in Canada is that old system that existed when I was born... When, clearly, the container they're looking at was produced or imported from the USA, and is using the smaller US gallon, often with the corresponding litre conversion both marked on the containers.

[@ingojochl9444]

You can have a tight tolerance but still have a loose fit, if the parts are +/- 0.005mm but have a clearance of 2mm. They are precisely made, but have lots of slop and play. FIT is the relationship between parts and clearance taking tolerance into consideration. You can even have a negative clearance, which is a press fit, but you need to hold close tolerances to achieve or it’ll be loose and not stay in place or too tight and bind or break.)

[@TylerHicksWright]

There's also a #10 screw that's very commonly used. The best way to understand the imperial system is to think about it like the English language. It's an archaic amalgamation of standards from different systems. Similar to how English smashes together Latin, French, Greek, and, Germanic other languages, the imperial system smashes together different measurement standards. The numbered screws refer to the wire gauge of the solid part of the screw, whereas the fractional screws measure the outer diameter, the second number indicating thread pitch. Then you have obsolete (but still present in some older British vehicles) standards like Whitworth, that were the precursor to the fractional standards, but where the head size was the fraction and the outer diameter was some roundish number like 0.400 inches. But when you're putting 1 into 12 into 5280 as your system of lengths and distances, the fastener standard really isn't so bad.

[@chrstphrr]

Sounds like we need to grab those few oddball fasteners Alexandre wasn't able to get ahold of, and mail him a little "care package" of the remaining oddball Imperial stuff. I'd only heard on occasion, about the old British standards. *really* think if someone needs BST or Whitworth, that should be left as "an exercise for the viewer to complete and share". Same with perhaps other threaded systems like AN-fittings and NPT (National Pipe Thread), UNF, etc., etc.

[@aantony]

if someone is adding this, #10 is 0.190in, i guess call it 6/32 too Also "wire gauge" is not the best language to compare to since "wire gauge" goes in the opposite direction.

[@GregJoughin]

I'm at 4:12, and the answer to everything so far is "Machinery's Handbook." Sizes for things like clearances, tolerances, allowances (for wrenches, etc.) are all tabulated for just about every fastener and situation known to mankind.

[@sometimesinfocus]

And I'm sure everything in said handbook holds true for CNC'd and drilled holes and whatnot...basically for anything with a DIN/ISO/whatever standard. 3D printing is a bit more individual than that, cause the tolerances can depend on anything from motors and belts (mechanical components) all the way to temperature and flowrate (software parameters). The slip-fit on his M8 nut might be a press-fit in my situation. Long story short, there's a some trial and error that needs to happen in order to find the tolerances for your own machine.

[@tallAldiProduction]

I have such a table book laying on my desk besides my caliper and use it at every design I 3d print. Also most CAD programs also have the norms included as features so you don’t have to for example design recesses for screws by hand. As for slip fits I basically once determined the specific clearance needed for my printer and saved it in my basic preset. Now I can simply use it as an offset to the official norm parts. I’ve been doing this for years and it’s working great.

[@pan6593]

yes mate BUT not every screw, bolt and nut are the same size. Have you ever bought a set of m5 bolts on Amazon (probably made in China) and then bought another set for the next project at home depot? They might not be the same size. So if I want to print something and create the 3D model I can literally test the holes of my print and know who I need to draw it... Of course you have to do this for each 3D printer you are using in case you have more than one. Even if you change filament or temperature your 3D print may vary and bolts will not fit anymore.... That's what this video is about. Not about books, tables or XLS sheets that's useless unless you want to print 3 prototypes because you used the numbers from the book.

[@AleksandrEfimov]

Good thing about this tools is that if you print them on the same printer as you're planning to print real parts, it will automatically inherit all imperfectnesses/precision problems of the printer. So you can model exactly for your printer even if it's not perfect

[@MitsumaYT]

Yes and no, technically you would need to do that for each material on that printer. Since different materials have different shrinking factors if you haven't calibrated that all to one standard already.

[@MitsumaYT]

Very neat to have. As somebody who works with Blender3D most of the time, I simply have created myself a library of boolean models over the time on stuff I use. Like a caphead screw is basically two cylinders, if I need throughhole or certain depth I can expand the cylinders in length and the boolean modifier will "cut out" the proper hole in the end. They already include the tolerance as well.

[@Qualitaetsnutzer]

I've been 3d printing and using cad for 6 years, and I've literally never needed this. Either I use a machinist handbook, or I just use my calipers and add 0.2mm for the tolerance of my printer. I do, however, like the tolerance test board. The solution to figuring out what thread a bolt is is learning a trade and letting yourself be shamed by your colleagues for getting the thread wrong.

because 3d prints are usually 75-85% empty space inside (there are some patterns, but i’m not going into that, look for infill if you care to know more). every side that is external has usually 2-3 walls of plastic before you go to infill, unless you increased it. if you reach the infill, you won’t have strength anymore.

[@TheJacklwilliams]

@@zuppy2 Agreed, well aware of the infill and walls issues. They can be configured to accomodate mild adjustments however if this isn’t taken into account, yeah you’d have problems. I agree more, on Alexandre’s approach as to making it right off the build plate. It is, tantamount to painting 3d printed items when you can, print in the color(s) that you want and not need to paint them. However, as in all things, there are situations where painting happens.

[@darbodrake89]

He should have a larger wall count anyway to account for fatigue

[@rolando_j_]

@@CGT80 it's all about wall thickness. 3D prints, particularly fused filaments which are the most commonly used, aren't solid. They are walls with a lattice structure between the walls. If you strip away the entire wall, with a larger bore, your lattice is compromised because the walls are structural to the lattice. Generally you have some control over the thickness of the walls, but you generally don't want to increase the thickness of walls as it increases the amount of filament and cost that your print will cost. It also increases the time it takes for the printing to take place. There are solid 3D printing methods. The first 3D printing was SLA or Stereolithography produces a solid model. But this is much more costly way to 3D print than fusing filaments through a nozzle.

As someone who has grown up in a country using the imperial system it's no more confusing than the metric system as long as you don't try too over think it. Under a quarter inch bolt the sizes are numbered ie 6, 8, 10, 12. Then you start going by the fraction of an inch. After the size you have the denominator for threads per inch, ie 32, 24, 20, 16. Examples being, #10-24 and 3/8-16. We also have coarse and fine threads, ie. 1/4-20 unc and 1/4-24 unf.

Metric has fine thread versions, but in my experience (granted I am also American, but work as an engineer for a global manufacturing company so I deal with both systems daily) metric uses the default sizes like 99.9% of the time.

@@johanhalvarsson2148 Fractions aren't for lazy people and if you become familiar with fractions, you will understand them enough to quickly figure out the next common size. Fractions for us are kind of like the base 10 system you use of unit, 1/10th, 1/100th, and 1/1000th of the unit as in meter, decimeter, centimeter, and milimeter. Down to 8ths or 16ths of an inch, it isn't too bad, but for many of us it is awkward to remember 32nds and 64ths. For machining, I like to work completely in thousandths. Metric has it's advantages, but our machines are not built for the metric system, nor is the tooling, or existing parts and building practices. We would have stupid random metric numbers to equal what we use now, so it would be very expensive and a royal pain for people to learn to switch over.

One, friends don't let friends use tinkercad. Use Fusion 360 or any of the free parametric modelers. (other than freecad, it is designed to be terrible to use.) Two, just about every slicer has automatic conversion these days so it doesn't matter what units you are modeling in. Three, the US customary system is superior for anything larger than a grape to the size of a house. Outside of those sizes, you should be careful letting yourself get an intuitive grasp on the dimensions as that is where a lot of mistakes happen. The US system is designed to work with fractional inches as the smallest "base size" and then thousandths of an inch to give desired tolerance/fit. Fractional inches give you much more freedom of sizes than metric, often letting you do the design work without needing to use a calculator. Need to find the midwaypoint on a 5/8" line? Easy, multiply the 8 by 2 to get you 5/16". Conversely, enjoy getting the halfwaypoint on a 15.8mm line. One important thing to keep in mind is that the US customary system is designed such that you can work with discrete fractions, you shouldn't be designing things that are 1/7", but in metric, due to the limited discrete units, you can't do designs that are more than moderately complex using the same methodology, you will end up with 1.46mm for example. Base10 measurement systems are only good for unit conversions, base 12 is where it is at for actual designing. Base 8 and 16 can work well too.

Never used a 3d printer but I thought of that same solution the moment that you identified the issue so imagined how satisfied I was when I saw that you’ve already done the hard work 😂

[@eleanorhathaway3619]

awesome thanks for the free files. I have them downloaded already and on my to do list to print over the weekend. much love from the uk

[@The.MrFish]

Great work Alexandre! I would love it if you add the hole size for tapping as well!

[@renatovelarde422]

dang, these are so awesome, exactly what I needed on my last thing! I'm learning a bunch of this stuff from 0 and it comes fast but it's a lot of wasted plastic when you're not a trained engineer to begin with.

[@roberttrescott2741]

It's always great to watch an ALCH video! 3D printed circles are inherently problematic since there doesn't appear to be a consistent compensation to account for the width of the track being laid down. Smaller holes can get really plugged up while larger holes get by with a bit of tolerance. It seems there's always a bit of trial and error in the design. The templates are a great idea, but I'd need one for each printer and for each type of filament, to make the fits perfect!

[@hulpe]

you can try polyholes :P that seems to be way more accurate and looks almost round if you alternate it^^

[@roberttrescott2741]

@@hulpe what would be really nice, is if slicers used a compensation algorithm that behaves like cutter compensation we use on CNC mills. Then maybe our holes and cylinders could match their design dimensions. Cheers!

[@edwardpaulsen1074]

Greetings! Love these models and will likely get these because I like them a bit better than the current ones I have... I am an engineer and have to swap between Metric and Imperial units constantly depending on where parts are sourced and availability... I do most conversions in my head now and only verify if it is critical tolerances. I can shed a bit of light on the Imperial numbering... larger fasteners follow the fractional logic based on one inch, but finer bolts would descend into quite a mess of ever larger fractions quickly... not to mention that early bolt manufacturers used coils of standard wire gauge and then cut (or formed) the threads and used a sort of riveting or hammer process to flatten out the head using a die... therefore we get #12, #10, #8, #6, and even #4 and #2 for tiny machine screws... these are NOT to be confused with electrical wire gauges made for copper and having a different set of properties and parameters... (so bloody complicated at times!) But, that was the way it was, with many competing standards until eventually a few shook out as dominant overall. Even so, there are still a few feuds about the "best types" depending on the usage and personal preferences! LOL I am somewhat a chameleon as I use whatever is best for the overall project and either aligns with the most common measurement system in use for the project, or what the customer desires or specifies.

[@AllenZee]

you are a god among men In about 2-5 years time when people find this video & the templates - statues will be built. That is all. Thank you

[@snuurtje]

Ty for this Alexandre, really useful. Found myself indeed repeating the same measurements multiple times.

[@MCsCreations]

Fantastic work, Alexandre! Thanks SO much! 😃 Stay safe there with your family! 🖖😊

[@m97120]

In certain CAD programs (Onshape, for example) you can create a document with variables for all your common hardware dimensions and then use that across all your projects as a linked document. So when figure out better dimensions later on you can update it in one central place and it'll update it in all your projects. So you don't have to wonder about the dimensions again for each project.

[@ti0chema]

You are a 3D printing genius sir. New subscriber here and yes I’m downloading right now!,

[@jmforeman02]

As an American, I cannot possibly explain how imperial is better. It isn't, but it's often cheaper and easier to use just because there is greater supply here. Also all our materials come sized in imperial: lumber, drywall, acrylic, etc. If it makes you feel better, a lot of us can also use metric and for some things we have to.

[@shawnholton5182]

Was going to say that you can get dimensions on McMaster but I love the idea of actually holding the thing in your hand. Thank you.

[@PetesGuide]

15:55 the US used to have both #10 and 1/4” screws! Very slightly different: A #10 screw has a thread diameter of 0.190 in and 24 threads per inch. A 1/4-20 screw has a 1/4" diameter and 20 threads per inch.

[@LouisArce-n1u]

Use " fluted reamers " that are used in machining metal for enlarging holes or drill them out. Reamers will allow for tight fit or loose fit depending on tolerances. They also make expanding / adjustable reamers.

[@inund8]

I really like your ad disclaimer right at the top of the video. Very admirable.

[@billd6793]

It is great that you went through all this work to create these fit models. I recommend not printing them and create your hardware CAD file with the cut tool built in. Now you can import your required file to your new model, position it and use the built-in tool to subtract from your model. This will save you tons of time modeling.

[@ohallifax]

So lovely to give away things like this Alex - sure they'll come in very handy for so many people. Thank you. Now go back to making bigger projects for us to enjoy :)

[@matthysloedolff]

Tusen takk, Alex! Det er fantastisk! These are probably some of the most useful tools I've seen anyone make for a 3D printer. In Australia, I have access to both metric and "freedom unit" parts. I almost exclusively use metric though.

[@jwrm22]

Thanks for making these files available. The next step is likely just to have a library. As in, place the hardware in the design, subtract the hardware from the design, and you are done. I don't know how common this is in 3D CAD, but it's what I do in OpenSCAD, and what electrical engineers do all day.

[@TheGrimmindustries]

Thank you for sharing the files. I primarily use resin printers and I'm going to print it on them.

[@builderjake8991]

Great Video! Thank you for your work, this is very helpful for those of us who are starting our design journey.

[@ambuj.k]

Kudos to Alexandre for being a good sport and being honest about the pricing of his models and making free to download for everyone!

[@JohnDoe-mg7ht]

Our freedom units, also include "fine" vs. "coarse" threads for the various screw/nut sizes...

[@stvcolwill]

Metric also has several thread variants as well. some are more commonly used.

[@johnlytle6633]

I forgot about fixing the STL function of the slicer. The repair STL function reported that the file was nor repaired, however it did work to fix the problem I was having. These are really going to come in handy, thanks. I plan on using these to assist with my RC modeling. It would be great to have a board for 2.0 and 2.5 mm fasteners. Maybe I will work on that. I'm unable to slice the M3 board. It looks fine when I import it but when I slice it all the printing is not visible. I tried it with Prusa, Qidi and Orca with the same result. I imported it into Fusion 360 and exported it and that fixed the problem but changed the dimensions of the model. I'm not sure what is wrong with the .STL file but I did not have any issues with the M4 or M5 boards. They came out great. Thank you for posting this.

[@simonvongunten9288]

Thank you for the great files. I run into the same problem as you all the time, so it makes total sense to print these and have them around while designing! 👍

[@Sharp_Stone]

Thanks for the idea! I don't have square nuts in my arsenal but I do have captive nuts so I'm gonna take this idea and make my own version!! Thanks 🎉

[@the1legend118]

I purchased two of your box sets in the past. It's awesome that you made this one for free, thanks! I'm from the US so I have spent most of my life thinking in freedom units but when I got into 3D printing I really wanted to understand metric so that is how I think in the 3D virtual world. But in the real world, I still think in freedom units. 😂

[@JointerMark]

Thank you for developing this! And especially thank you for making them available for free!

[@samuelebortolozzo3754]

these models are awesome. what a great job! I think I will make similar ones for the compressed air fittings. thanks for your work from Italy 😎

[@WilliamHoeft]

Thank you! Good video and very nice design on the templates. These are going to be very useful to use. Looks like a lot of time (yours and the printers) went into creating these. I'm not sure if I have seen any of your previous videos, but it is a safe bet I will now. Thank you for providing these for free.

[@GeneralPurposeVehicl]

The kicker is that you may need to tweak these on a per material basis. You may also find the holes to be a different size than marked in the gauges.

[@Brocknoviatch]

Extra Tip: Dry your filament for consistent hole sizes. I have found that wet filament changes dimensions of the final printed part.

[@firehound497]

Really like your content and thanks for the free files!!! Got my first 3D printer, a Bambu A1 a month ago and looking for content. Keep up the great work.

[@markhoward3851]

Great videos, keep up the great work! "Stuck with the Imperial system" Too funny. I remember learning Metric in grade school in the 70's. Here I am in the Engineering field in my 50's and we are still on Freedom Units. Both my sons are Engineers also, and are frustrated by the lack of Metric here. Oh well, maybe when they're 50?

[@ronaldmorrison2765]

At 72 years of age and American, I have used SAE bolt and nuts for the last 65 or so years. I think in Imperial measurements. I prefer to design in metric so this set of prints should really help. Thanks.

[@alexrobles7744]

Great video, thanks for making this and for free. I am appreciative of you making for the units we use here in the USA. How many USA makers don't bother making it for metric also. again thank you

[@victorgrandamancebo5582]

thx you, allways nice to see your curiosity and ingenuity. I cant belive you dont have at least a million subs!

[@YensR]

The hole sizes are key, especially in the different orientations Alexandre shows. Also, the STL setting (how many facets upon exporting from CAD) matters, because you approximate a circle with straight lines. I also recommend getting a set of drill bits, so instead of re-printing a part, you can modify it. Not suitable for mass production, of course, but this cuts down on cost, time and plastic waste.

[@peternorthway235]

Thanks Alexandre for making these available free of charge. As a 77 year old pensioner I have to save all my pennies for filament :D

[@secretwpn]

Regarding printing holes without supports and the top part collapsing - try making the hole shaped like teardrop - keeping the bottom part perfectly circular but adding a little "tail" on the top. This can prevent the top collapsing

[@forster46]

These are awesome. I still can't 3d model on anything but sketchup to save my life, but one day when I take the time to learn I will come back to print these.

[@NWGR]

Hey Alexandre, just a heads up; the M3 design board has some errors in the print file. Looks like hex nut thickness, counterbore thickness, counterbore +washer thickness are from the M8 design board.

[@MrMalaman]

to print without support, i have also a tip that i use all the time : I add a layer of 0.2mm which completely fills the hole, and allows a classic bridge filling. then the screw cracks this thin layer easily

[@KulawyMan]

Sorry, the sun got in my eyes - "a layer of 0.2mm which completely fills the hole ... " - can you elaborate on that a little, I can't seem to visualize what you're saying. Always looking for these kinds of tips, so thanks in advance for tolerating an idiot. :)

[@myriadtechrepair1191]

That method is the one I thought he was going to mention. It is inferior though as it requires post processing.

[@MrMalaman]

@@KulawyMan sorry I speak bad English. I will try differently. at the level of the bridge layer, you have to fill the hole by making an extrusion (of the hole diameter) of 0.2mm. in this way, it becomes just a normal bridge with a rectilinear filling. and as the layer is very thin, it breaks when pushing the screw into it.

[@MrMalaman]

@@myriadtechrepair1191 i think my explication is bad, i have not post processing
