button wells for hoolyhoo's back button board

thingiverse

This is a button well plate for the back of a Gameboy Zero or Kite's Circuit Sword build. I designed it after I had already drilled my own holes, so it's not 100% symmetrical - but still very close. I would have made it first, but I didn't know I needed it until I had the buttons in place and realized they were too wobbly for my liking. I've included a drill guide that you can drop into the wells to mark the holes with a fine liner so you can get them in the right spot to match the wells. Or if you're able to design your own parts, feel free to use my idea and create one that is symmetrical. There's a small flat shim that gets glued to the underside of the wells to account for the recess in the DMG shell. It's easy to print this separately than trying to print it upside down with supports. I also found that the SNES style buttons (concave) required a slightly bigger cap insert. I've included both sizes: 7.3mm for the DMG buttons and 7.5mm for the SNES buttons. Mine were a snap-in fit, but glue is an option as well. You can always play with scale if your printer doesn't print the same as mine - just don't scale them in height at all. And this will work with the cartridge fan as well.
