I lost the protection piece for my centre support on my bike somewhere and made this replacement.
Printed this using TPU since the original part is flexible. My TPU is quite old, so the print quality is garbage on my print, but it works. The model can easily be printed face down, since there aren’t any super bad angles.

The models can be simply pushed onto the rod of the centre support. Therefore I guess they will also fit other bike stands or support types for bicycles, but this I have not been able to test.
Also included STEP file for easy modification in other programs than Fusion 360.
