Summary

This is two things in one. The lazy susan base can be re-used for other projects where you need something that rotates with very little friction.

The gaming trays are supplied in two sizes, small and large, and with different numbers of sections.

Print the lazy susan with higher detail so that the balls have a smooth track. After printing check that the track is smooth and sand down any bumps you can feel with your finger.

You will need a M3 x 10 mm long flat head screw to hold the lazy susan together. The top part is threaded for M3 in the model so there is no need to tap the hole. You will also need 6mm balls for the lazy susan. Plastic Airsoft BBs are ideal.

Notes:
Orient the lazy susan parts so that the ball tracks are facing up. I used clear PLA for the lazy susan because it is more crystalline (harder) than pigmented PLA. Make sure the tracks in the lazy susan are smooth. Use enough balls to fill the track but not to crowd them. Insert the screw and tighten until the mechanism is just starting to tighten against the balls and then back the screw off until it spins freely.

I suggest printing the lazy susan with 0.10 mm layers (fine setting) and the tray with 0.20 (medium). The trays are optimized for 0.4 mm nozzle width.

The trays will need supports from the build plate for the hollow inside and the curved outer tray edges.
