I created this adapter to be able to use automatic focusing during my astrophotography sessions. A small Nema 17 motor is driven by an Arduino running Arduino ASCOM Focuser Pro2 DIY download | SourceForge.net and is controlled by N.I.N.A. Nighttime Imaging 'N' Astronomy – An astrophotography imaging suite (nighttime-imaging.eu).
The motor is connected via a belt to a pulley which replaces one of the original focuser knobs. The whole assembly is held in place by the large screw in the middle of the focuser.
I added the OpenSCAD files so you can modify the model to fit your needs.
EDIT: I uploaded another version with longer holes, this allows for more adjustment.
