This is a high-profile 60% keyboard case compatible with Pokers, WKL b.face, and Gon Nerd60 pcbs as well as any other pcbs with identical mounting holes and USB placement. It requires 6 heat-set threaded brass inserts (McMaster-Carr part 94180A312 ) and m2 screws. After printing, use a soldering iron and a small screwdriver to melt the inserts in to place in the holes.
