The file 'Telescope EQ Mount Motorized Star Tracking (Meade Polaris 127) 3D Printer Model' is (stl,scad) file type, size is 1.2MB.
This is my solution to motorize R.A. axis on stock telescope EQ mount. No irrevisible modofications of the mount needed. Just print and snap it on.
It includes:
Also there is a relatively simple arduino project that you can build without soldering or wiring using cheap 3d printer parts, if you don't want to integrate it with any astronomy software or setting up OnStep.

It whould probably work on similar telescope mounts. I'll share f3d/step files later, so you can adjust it for your mount, motor shaft and gear ratio.
