rubber feet

We have a glass "cutting board" that had little rubber feet glues to the bottom. well the feet kept falling off and i was done reattaching it every week so i made these. these feet hold much better and are more robust. they have a 4.8mm opening which is a perfect tight fit for the board we have.

I printed 4 of these with TPU on my Ender 3 at 30mm/s with no supports.
