Half Squash Ball Foot

I liked the original but wanted to put some under the Z-extrusions on my Ender 3 Max.

Tweaks:

Prints a little faster, I made the walls 1.2mm thick for every layer after the base so there's no infill or weird voids.

Two holes for M3 screws with T-nuts and two for M4 screws

Edges are chamfered to help clear electronics panels
