This is basic ceiling mount for standard PIR / occupancy sensor. Also happens to be my first 3D solid model. I printed it with Wanhao Duplicator i3 Plus.

You need to rotate the model upside-down (180 deg.) in Cura before sending it to 3D printer. I will add support for customizer and with correctly rotated in next update.

For installation:
Make 62mm diameter hole in ceiling for this 60mm mount.
The sensor hole is 23mm diameter.
