35cm collapsible lazy susan (thrust) bearing

thingiverse

This is a 35cm (13.8") lazy susan a.k.a thrust bearing printable on an 18x18cm (e.g. Prusa Mini) bed. You will need: - 8 prints of the base tile - 4 prints of cage tile - 20 8mm bearing balls The dovetail joints are stable enough that they don't have to be glued together (though it would certainly help). My 20% infill prototype tested fine unglued with 200 lbs. on it. There is no support in the middle, so you'd need a stiff tray for central or uneven loads. There is a 2mm hole in the center for a screw/nut pair for radial stability, though with heavy loads I haven't needed it. Joint tolerances are 0.1mm. The pieces from my printer fit together easily.
