A jig to assist in notching a pro controller faceplate for Smash or other fighting games.
Print with 3 or more shells.
After printing, disassemble your pro controller until you can remove the faceplate. Once the faceplate is removed, remove the two screws and the ribbon cable holding the shoulder button assembly on. Insert the jig into the left analog stick hole and be sure to align the tab with the cutout in the stick hole. File the faceplate until the file is flat against the jig face. Do this for all 8 sides. I would suggest using a file with safe edges, although this is not necessary.
