Hitch Ball Cover
Description
This cover was designed to protect your shins from painful bruises from the hitch. When you print this, be aware that the purpose of the cover is to provide a cushion. Therefor, you absolutely need a flexible material, as well as an infill type that supports the flexibility. I used TPU 95A, with 15% infill and concentric infill pattern. I also tried a more conventional grid pattern, but that did NOT work. I was not even able to put it over the hitch. With a grid infill, it was way to stiff anyway, so it would not have provided much protection. I designed the thing using FreeCAD, and I provide the Freecad file, as well as a step file, as a convenience for everybody who wants to improve or otherwise modify the design.
