See my [github](https://github.com/yeckel/ESPSatTracker) repository for ESP32 bluetooth rotator controlling SW.

I thing the building process is pretty clear.
+ Print the corners of the cube
+ cut the 20mm tube to 12 20cm long pieces
+ connect pieces to the frame
+ add 4 plywood walls so they fit
+ drill holes for axis slightly smaller then the bearing is
+ attach gears
+ add gear to the stepp
