Nắp Che Mâm Xoay Planet Unknown S.U.S.A.N.

This is a quick and dirty solution to the tiles falling out of the lazy susan in Planet Unknown. I put these on, then the rule book on top, and then the game box. So far it has passed the vigorous shake test.

Print at 0.28 layer height. I use no top/bottom layers and gyroid infill - 2 of them print in an hour.
