Rotating display table - USB powered, with light

160 mm diameter rotating display table; to present/show-off products or things. USB powered motor and light. Please read assembly instructions before building -- left as "work in progress" because of the mechanical assembly process (but if you've built a 3D printer, this shouldn't be too challenging). Power from anything other than a charger or powerbank at your own risk.

[ UPDATE 19/09/17: Added zipped IGES CAD files and turntable V2 STL ]

Assembly:
1) Print the large base (large flat side down)

2) Print the large turntable/worm-gear (a large flat side down)

3) Check the fit of the turntable to the base. The base's central post may have a nub to be trimmed at one quadrant (if your retract on layer change isn't sufficient). The turntable should spin smoothly. Don't install a screw yet, remove the turntable.

4) Print the motor spacer; either GM 20 or 130 version. The GM20 is for a gear-head motor that will provide a more suitable RPM. The worm stage gives ~ 150:1 reduction ... so a 300 RPM gear-head motor will provide about 2 RPM at the table.

5) Mount the motor to the base using M3 x 5 screws (3X). The screws are essentially self-tapping.

6) Hack a USB cable to power the motor (red and black wires, model rendering incorrectly shows green). Before soldering the wires,…
