I have designed a small model to connect my Raspberry Pi 4 with a small touchscreen. Since I might want to use the screen for other things, it can be removed from the mount and connected elsewhere.

The screen I am using is this one:

The mount is designed so that the screen fits perfectly, and the lid is held in place by friction. The case for the Raspberry Pi has screw holes where you can attach a case for the Raspberry Pi or mount the Raspberry Pi directly. I used M2 screws. The lid for the Raspberry Pi case can either be simply placed on top, glued, or screwed in place. There are place for 4 Magnets (6x3mm) in total to hold the Screen Mount to the Raspberry Case. They have to be glued in.

All parts can be printed without supports, except for the front part of the screen mount.
