Snap-in Toolless Squash ball Feet for Prusa MK4

I liked the design and the extra height from Yos's model but didn't want to fiddle around with t-nuts. I took the half of the design that snaps into the 3030 extrusion from Osfald's model and it works great. The printer moves around more but it no longer transfers noise to my tabletop. The back feet won't fit on the outside of the MK4 due to the power supply and control box. Those feet can be mounted inside the frame without getting in the way of anything.
