Rotating Bowling Ball Cup

3/04/2019 - A new Version2 file has been added, which replaces the original base file and eliminates the need for the bearing retainer component. This simplifies the design significantly, allowing you to simply insert the skate bearing from the bottom of the new base. The small hole in the ball cup, combined with the four small holes in the base, provides a way to place a pin through the holes, enabling stationary use of the ball cup. If the nut seems too tight, scale it by about 1.008% in Cura or your slicing software when generating the GCODE. There is only one ball bearing spacer defined in the .stl file. You should flip the spacer over on its flat side and create seven copies in Cura prior to generating the GCODE. The Base, Ball Cup, and Ball Bearing Spacers should be printed with 30% infill. All other components should be printed at 100% infill.

You could also attach a base plate to the top and use it as a "Lazy Susan." Comments are welcome and appreciated.
