This machine is driven by a Nema 17 stepper motor. The shaft is in one piece with the 64z pulley, so it is very easy and reliable to print. The thread is suitable for the additional chuck of the Proxxon micro-lathe DB 250. https://www.proxxon.com/de/micromot/27020.php Make sure, to print the threaded section with a layer height of max. 0,1 mm, 0,08 mm would be better.
The ball bearings are 32x20x7 mm, I've uploaded the shaft with three different tolerances, so you can chose, which is the best for your printer to make a perfect fit to the bearings.
The screws for the clamps are sheet-metal-screws 2,9 x 13 mm.

It is in German, but you will understand what it's about.
