Lazy Susan Turntable Bearing using Cylindrical Spacers

thingiverse

This is a "lazy susan" turntable bearing using cylindrical 1/4" spacers instead of spherical ball bearings. A single screw with a washer can be placed through the center recessed area to attach it, and also hold the bearing together. (Additional screw holes are provided for attaching if desired) I didn't have ball bearings but I just happened to have bunch of 1/4"x1/4" nylon spacers so that's what I designed it to use. You can print the spacers as well (they're included in one of the STL files). Default dimensions are for a 200mm diameter x 20mm height turntable bearing, using 20 spacers. The optional "height_increaser" (either 200mm diameter & 215mm diameter version) adds 10mm of height if attached. If you download the single "turntable" STL files, use the "split" option in Slic3r to separate the pieces to print them separately on the print bed. SCAD file included for additional customization. Note that the "keeper" slides around inside the race with a little friction, so a smoother outer layer is better (repeated turning will loosen it up in any case).
