Squash Ball Elephant Feet

This is the Squash Ball Elephant Feet.

I use it underneath my Prusa MK3S+.

I tried different squash ball solutions, but they all break on me (or I just use to much force). So decided to design one that just sits under the frame, taking the weight directly from above. You place a squash ball inside the cup, and place the holder underneath the frame gently. You can place more feet if preferred. Im using 5, two at the front, two at the back, and an extra one near the PCU.

I print with Prusament PETG, but you can probably print this just as simple with PLA. In PrusaSlicer using the default 0.20mm QUALITY profile. No support and no brim, 15% infill. I used 4 perimeters. Did not test with other settings. 

There are two versions, with and without a hole in the middle. With the hole is designed so it will print easier on the overhangs. But the one without the hole print good enough (a little sloppy on the last overhang). I find the one without the hole has an extra function, it will keep the ball in place because of suction within the cup.

Hope you like it.
