I actually created this in TinkerCAD, though I had a hard time getting it done. TinkerCAD doesn't seem very intuitive.

In this case, the base plate is just there for support. 20mm x 20mm x 5mm with a 5mm post that has a 2mm hole in it.

It only took a few minutes to print this little demo block.

I have these machine screws that fit perfectly in LCD and OLED modules and they screw nicely into the 2mm hole.

The 2mm hole goes all the way down the 10mm post, however the screw is maybe 4mm long. Again, this is just an experiment.
Nice. Working on getting rid of some more of my antique computers so that I can set up my printer. Keep an eye on the sales board. ;)

Post all you want, sir! I will share them on social media (Facebook, Instagram, Mastodon and Bluesky).
I'm continuing to experiment with the various screws I want to use to mount hardware to 3D printed stuff, specifically displays. The first model I posted worked perfect for a very small machine screw originally intended to mount the 0.96" OLED. This screw is still actually slightly too big for that display, however my point was that the original screw for the LCD was too big for the 2mm hole, so I used the smaller screw.

In any event, I made another model tonight having increased the hole to 2.6mm and now the original size screw fits perfect. So I am making notes on hole:screw sizing. Which screws require which size holes.

That will come in handy.

I've done the equivalent on the laser cutter by using scraps of material to cut or etch test patterns. In this case, test cuts of holes for various screw sizes to see how accurate the cuts are because of the kerf.

This scrap has test holes cut for #4-40, #6-32, #8-32 and #10-32 screws. The CAD hole dimensions are listed and etched into the scrap wood as well.
