Quarterturn wall mount for (not only) Garmin devices

To store some bike accessories at home, I wanted to have some kind of Garmin/Quarterturn mount for a cabinet or wardrobe. While it's difficult to print a whole Garmin mount with its undercuts, i figured out that having just the bayonet ring is enough for a secure fit at home. And this way it's way easier to print. I'm using it for heavy Magicshine bike lights and I'd say the fit is strong and secure.

Attached you'll find a big version for standard Garmin, Magicshine etc. devices as well as the “small quarterturn mount” which is often used for small bike lights e.g. from Magicshine. Both mounts work well with 3mm screws such as Spax 3mm Panheads.

Very important for printing: please print the mount upside down! Which means, the device-facing side should be the first printing layer on the bed, the wall-facing side should be the last. Should usually work without supports.
