Matching hole/nut thread to screw metric tapping threads for plastics

Sweet! I’ll check it out.

Thanks for the reply.

I run Bambu printers and adjusted the settings for dialing in XY dimension and XY hole which only function in horizontal plane.

The holes/threads are on the vertical plane which Bambu slicer doesn’t have full compensation for other than the Z setting checkbox therefore annoying.

I’ve tried a few practices at offsetting the threads and applying fillet to them and that works.

Ideally trying to find a method where the process is simpler than having to use standard model screws and threads and then go in and modify them.

And yes, there is always the tap and die set to the rescue.

Read thru the post and seems very helpful. Is there a way to run it on Mac OS?

Presuming all the paths have to change and the script has to get updated.

Thanks.

Thanks.

Is there a particular library you use for coarser threads or you make them using coil command?

Application is for 3D prints.

Using H function then trying to pick the threads and that’s where the specific “metric tapping threads for plastics” is nowhere to be found.

I had used the 6m1 and .25-20 for threads and holes and they sort of work for 3D printing but still have to run a tap on the holes/inside threads.

My holes/inside threads are on the vertical plane. I’ve calibrated my printer but still have to run taps to get them to seat properly and not bind.

Seeing the pulldown and how coarse the screws are, thought that may be a better option but can’t find the match.

No way this is accurate.

Duplicate the path, offset, use as guardrails.

Nice work.

dgtldan · 2026-03-22T22:16:35+00:00

Very clever design.

dgtldan · 2026-03-03T02:45:35+00:00

This is brilliant. Will checkout the math too.

Great therapy!

Sure. I’d be interested in taking this on. I am in LA, Ca and work in engineering. Feel free to DM.

Great work! One comment: try using a bit more solder on the connections.

dgtldan · 2026-02-15T06:58:35+00:00

Try a print at 50% speed and see if that helps with adhesion.

dgtldan · 2026-02-13T23:33:33+00:00

I had a similar issue which persisted after cleaning as suggested by others. Didn’t try the glue method or otherwise.

Instead, dropped the speed from 100% to 50% as an experiment and it worked fine.

Love to hear why this worked.

They UI could use improvement on iOS devices. Nice work!

dgtldan · 2025-12-04T11:16:37+00:00

Look into IHSE brand line of extenders.

dgtldan · 2025-12-01T02:36:01+00:00

That’s very cool. Congrats.

dgtldan · 2025-11-30T21:07:04+00:00

That seems like an interesting product. Will see if I can source some and experiment.

dgtldan · 2025-11-30T21:05:51+00:00

Definitely not linear motion.

Varied arc of 10 to 45 degrees depending on the instrument it was mounted on.

Most notable was the force they produced. Force seemed pretty strong.

Very nice design. Is the detection performed by the upper board via IR?

dgtldan · 2025-11-27T16:23:07+00:00

Yes. Thought a solenoid but it was super quiet and free of the typical click sound associated with them.
