Here is my latest ESP32c3 & LD2410c Presence Sensor Case including wall mount, everything snaps together.

Added an optional wall-mount bracket as a separate file. The original case is unchanged.

Opps had the interior of the house painted and the painters threw away the camera ceiling mount. I had neatly boxed and stored the camera so the painters had no idea what it was. No problem I modeled a new one in Blender and after 14 minutes of printing a nice ceiling mount.
