I've made this feet for PS4 in a simple "classic" design for dual extruder printers. Of course it can be printed on single extruder printers. Central part was printed using wood PLA filament, top, bottom and symbols (circle, triangle, square, x) using black PLA. After printing I sanded these feet. Feet lifted up PlayStation high enough to prevent overheating.
Each foot consists of four files to be able to print with a dual extruder printer.
If you are new to dual extruder 3D printing than you need to upload 4 files, for instance "circle" files. After that chose extruder for each part, choose "arrange models" and finally "merge".
Good luck in printing! ;)
