Caster Cup

I designed this for my recliner chair on hardwood floors.

Specification:
- Inner Cup was made for 25mm.
- Outer Base is 39mm.
- 4mm in height.

Notes:
- I used the FIXA stickers from IKEA for the base, but I think there are other ways you could approach it.
- I did not know these were called Caster Cups at the time of designing it.

1/8/2020: Fixed the 1st circle layer issue. Realize it was 1mm above the surface in the design. Discovered it when creating stacking caster cup (remix).
