Autofocuser Motor Mount, coarse focus knob adapter with a 100T pulley for fine adjustment and endstop system designed specifically for the WO Star 71 Telescope. This project was developed to work seamlessly with the Arduino Focus Controller Pro sourceforge project, but it can be adapted to any autofocuser system. The NEMA 14 PG5 motor used in this design is paired with a 20T GT2 pinion for precise control. The 100T adapter is based on the openscad file found at Thingiverse, specifically designed for this application: http://www.thingiverse.com/thing:16627 A project box was also created to house the Arduino Nano, although it would need customization to accommodate individual wiring and setup preferences. The motor mount's design was completed in Fusion 360, except for the 100T pulley which was designed using this software as well.
