This is a door trim mount for the Sonoff SNZB-04 door sensor magnet component.
Original idea and design was found from espn8theocho's design found here: https://www.printables.com/model/704343-sonoff-snzb-04-spacersadapters (specifically the file "Body1-Trim3.stl"), however it needed to be resized and redsigned to suit my needs.
Additionally I used shindouj's design to mount the door sensor portion found here: https://www.printables.com/model/394896-sonoff-snzb-04-doorwindow-sensor-holder
Double side tape was used on both parts to fasten them to the door and trim.
The author marked this model as their own original creation.
