Agree, you can't use other peoples work but swapping DSM files is still an option.

NOT everybody has that attitude. It has stl export for your 3D printing.

@@RaymRaym-ri7lo You can't use other CAD other peoples work for free unless subscribing for 1 month only which is a cheap way out if only occasionally needing to use other CADs stuff. Or download and store up a few projects, then take a months subscription only. As you say DSM file sharing is a good option to get around that.

I agree. With DSM, if you haven't done single point threading on a lathe, the DSM method takes a bit to get your head around, especially if you wish to match existing thread standards. Working out what extra tolerances you need to allow for printer creep, adds further difficulty. The method I have described will make non standard matching threads, just pick your own diameter and tread pitch.

The printer we used for proving the setup, increased its sizes more on an external curve than an internal curve. Using those tolerances meant that printed nuts and bolts fitted their metal equivalents. That was the main point of the exercise, to produce a printed nut or bolt that was the same as the machine standard.

@@RaymRaym-ri7lo That makes sense - thanks for clarifying.

Tolerances used in the video where for an Ender3 using PLA. Different printers or filament may give different results. The process is to print a nut, adjust the tolerance for a nice fit to good quality metal bolt. Subtract the new tolerance from .6mm for the bolt tolerance. If the fit of the printed bolt to a metal nut is not to spec, adjust the bolt tolerance for a nice fit. This could mean a different tolerance than .6mm for different printer filament combinations.

Sounds like an interesting exercise. The principals should be similar. Try looking at the thread specs, they may give a hint. I only work with metric 60 degree so imperial is quite foreign to me.

Not quite sure what you mean but the length of the thread is entered in the dialogue box with the thread pitch and taper before you execute the operation to form the thread, or create the thread and form the the cap second.

I am mainly a mouse and menu person.

Cheers, make some suggestions and I'll see what I can do.

Thanks, will do! I've just posted another.

Hi, the hole ID for a nut needs to be smaller than the drill size and the shaft OD for the bolt needs to be smaller than the drill size as well, this gives the 0.6mm clearance in the 3D drawing. When printed, bolt threads have a large OD and nuts have a smaller ID so the clearance is tighter. The numbers only applies to threads to match them to fit standard metric nuts and bolts. You would need to experiment with clearances to have a good fit between bearings and shafts.

Try creating a plain along the line where you want the cut then use the split a solid tool. I am in the outback away from my desk until Sept. Will follow this up further then, if you can wait that long.

I have just posted a video on how to use the plane tool to split solids.

Glad it helped!

Thanks, make an inquiry if you need further clarification.

Glad you found it useful. the main reason for the post is that I couldn't find any tutorials that showed how to draw standard industry threads. All my prototypes were printed on a friends Ender3.
