I designed this foot as a direct replacement for the stock feet on Bencher paddles as well as others using this same design (MFJ, Vibroplex, etc.). As the OEM fdeet get older, they may get harder and result in a paddle that wants to slide around under use.

On the base of the paddle it uses the stock screws and has the same contact surface against the underside of the base, so no adjustments are required.

Since it's something that you want to be grippy, it should be printed in TPU. In terms of print settings, I used two walls and 15% concentric infill - however, I suggest you tweak settings to get the stiffness of your liking.  I used fuzzy skin so it would match my Bencher cover, but that is optional. The feet are designed with concentric rings on the bottom to give them a little extra grip to prevent sliding. They are also slightly taller than the OEM feet.
