So far I printed 2 of 6 big gear segments, and by tomorrow the missing ones will be finished. The motor mount and the small gear look good. For sideways support I'm using 608ZZ bearings and a small base. A 45-mm long screw holds the gear in place.

I'm thinking about painting the table surface but I'm not sure if it's worth the effort.

What is left to do:
 - add an index magnet and a hall sensor (design a mount)
 - start working on the firmware and wire the motor up
 - source lumber for the shelves, work on the shelf design
