Tuya door sensor alternative mounting plate

Summary A replacement mounting plate for Tuya Zigbee door sensors that use 2x AAA batteries. This custom plate features the same T-clip mounting system as the original but adds multiple screw holes and rounded corners for better mounting options and screw clearance. I needed to customize the original design to better math screws which where already present on my door from a previous sensor. Also the original design caused a short circuit because the screws line up with the battery contacts. With this design you can print a thicker mounting plate so the screw are deeper countersunk avoiding the contact.
