I found they failed after some years so I have buttressed the fail point on the sides and made the base thicker.

For the ender3v2 the front mk1-ender3v2-front-squash-ball-feet.stl is as is. For the rear it has a 1.1mm cutout due to the PSU plate. If you cannot print that cutout well use the original and the 1.1mm spacer provided as an alternative

orig-squash-ball.stl fits CR10S4 like printers
