This is a “snap-in” wall mount to hold a specific Raspberry Pi sized case.
I am using it with a Libre Le Potato in https://www.printables.com/model/338952-libre-computer-aml-s905x-cc-le-potato-base-case
It should also work with this case, which the one above is based on, but I haven't tested it: https://www.printables.com/model/24942-raspberry-pi-34-b-case
It is designed to be mounted in the orientation shown, or rotated 90 degrees ccw so the network cable is pointing downward. The Pi case is spaced away from the mounting surface to allow easy access to the micro SD card. There are tabs to keep the case from sliding out but it is easy to remove and replace the case.
There are two 0.2 inch diameter mounting holes spaced 2 inches apart.
It should import into the slicer in the correct orientation. No supports needed.
Designed in On Shape.
