Raquetball/Squash ball anti-vibration isolation foot flange

A simple flange for mounting a raquetball isolation foot to a flat surface. The mount grips the ball just enough to retain it when inverted. Mounts with a #8 (M5) bolt or woodscrew. (countersunk hole)

UPDATED: I added a version for use with a squash ball since they are more available outside the US. I made the fit a bit snugger to give the foot a little more load bearing since the squash ball is a bit squishier than a raquetball.
