Raspberry Pi Model B latching mounting plate.

thingiverse

I needed to be able to mount a Raspberry Pi with a Hat on it to a wall, and wanted it to be relatively maintainable. This is a mounting plate that screws to the rsapberry pi (I used M2.5 Nylon standoffs and nuts), and a couple of mounts that latch on to that plate. It has some play, but generally will hold everything in place. I printed this in PETG without a hitch.
