Happ lock

thingiverse

I built an arcade and bought a USB port that is shaped like a Happ button to go to the front of the cab. Unfortunately, the connector is too short for the thickness of the board, so it couldn't be screwed in from the inside. I designed this so that it fits a 30mm hole and it grabs on the button inside the panel instead of only on the outside. I'm not 100% certain it works on a Happ button since I didn't test it but it fit on the USB, so I'm calling this good enough. Let me know if it doesn't actually work with a Happ button and I'll fix it. Make sure you print External perimeters first, else the screw won't print right.
