Rotating Bowling Ball Cup

https://youtu.be/NFlSQjcTNQw Notes: 3/04/2019 - A new base version, Version2, has been added to replace the original base file and eliminate the need for a bearing retainer component. This simplifies the design by allowing the skate bearing to be inserted from the bottom of the new base. A small hole in the ball cup and four small holes in the base provide a place for a pin to hold the ball cup in position. If the nut feels too tight, scale it by 1.008% in Cura or your slicing software when generating the GCODE. There is only one ball bearing spacer defined in the .stl file, so flip the spacer over on its flat side and create seven copies in Cura before 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.
