This is a wall mount for a third party Galaxy Watch 4 charger. It might also fit the original charger, but I didn't try that.
It holds the watch at an angle. I suggest mounting it to the wall with some Tesa Power Strips/3m Command Strips. The printing orientation should ensure a very smooth backside to work well with this, if printed on glass or smooth PEI.
This thing was designed in FreeCAD Linkstage, version 2022.01.11, and the design process was streamed live on Twitch. Recordings of the streams are available on YouTube:
