Summary

RC work stand for 1/10 rc cars, based on a bearing 15x35x11
Base V2 does include shocks support, for shock cylinders up to 16.5 mm external diameter. Holes have been included in case oil is going into the support to ease the evacuation of the oil...
Both should be printable without support, base/baseV2 directly on the bed, while the top should be printed upside down.
Not printed yet, will be updated after printing.

Added a smaller base for smaller printer (I use a Creality Ender 5Plus, and while the base is printing, I thought it could make sense to make a smaller base).
