For a modular version of this rack see thing 2933751
This rack spins using 6mm Airsoft type plastic ball bearing. For the top I printed top side down using supports for the first 10mm. I did not use support for any other areas of the top. I used 3 shells and 8% infill and 0.32mm layers. Print time for the top was around 40 hours for the top. For the bottom I printed top down with supports in the bearing race but these probably are not necessary. M5 10mm screws will self tap if you are careful.
Note: I had a print quality issue with the top with ripples and a support pullout in the tray section which shows up as a small hole in the picture. Hopefully you know how to print better than I.
