I designed this mount for my Eufy C220 camera, but it seems to fit the C210 and S350 camera as well. Might also work for different eufy camera's.

You need 2 screws to attach it to a vertical surface, in my case the windowframe. But could also be used for walls or other places.
There are 2 versions. One with passtrough for the USB C cable, and one without. Use what suits you best.

The model prints without any support. I've added little triangles for the notches to print well without support. You can leave them or cut them away using an utility knife.
