Helical Gear Cup Base

The base included with the original didn't work for me. For some reason, it was sized larger than the cups. Second, the pegs didn't fit the bearings. Finally, when putting on the bearings, I snapped the pegs into the base. The pegs snapped in because I didn't want to put 80% infill throughout the entire thing.

This design has some advantages:

1. It uses significantly less material, but allows you to print the base much more densely.
2. The base is circles match the cup outer dimensions
3. It has little tabs for you to set your fingers on while you spin the cups
4. The hole in the peg will cause your slicer to put internal walls from the bottom to the top of the pegs, making them much stronger to the downward pressure of putting on the bearings.

Last, but no least, it prints a bit quicker :)
