(usage of jig not shown in video)

Print jig and align to DISASSEMBLED bottom shell housing for Game Boy Color. Should fit all make shells but may fit others better than some. Use (round) needle files to cut port hole out little at a time following the contour of the jig. Remove material slowly and check fit frequently. Finish with flat needle file to smooth out bottom of port.

Better files may work better but for $5, it's hard to complain about these: https://www.harborfreight.com/12-piece-precision-needle-file-set-4614.html
