There are 4 feet for each corner of the machine. The back left has a cutout for the energy chain to leave it untouched.
The feet have a feature to capture the existing aluminum bent sheet metal and hold them nicely.
Recommend many top layers, I did 10 at 0.2mm layer height. ABS with 6 walls with 25% gyroid infill and these feel solid on the machine.
