- 3/04/2019 - added a new base Version2 file that replaces the original base file and eliminates the need for the bearing retainer component. This greatly simplifies the design. Just insert the skate bearing from the bottom of the new base now.
- The small hole in the ball cup along with the four small holes in the base provide for a pin to be placed through the holes providing 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 7 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"

Hello, great design! Would 5/16th bearings work for this design? I ask as I only have 5/16th bearings on hand at the moment. Thanks.
I Just uploaded a new file, Base Version2. This new base replaces the original base file and eliminates the need for the bearing retainer component. This greatly simplifies the design. Just insert the skate bearing from the bottom of the new base now. Enjoy!
