A large turntable or "lazy susan" for photogrammetry of small objects or spray painting or cake decoration. Stable, with a smooth rotation. Designed to be screwed to a wooden rotation plate (in which case, print 2 of the "Base" files and flip one over) or used with the rotation plate here (in which case, print 1 "Base" and 1 "Lid").
Requires 12 marbles, standard US size of 14-15mm.
