Recessed Ring Alarm Contact Sensor

Ring Alarm Contact Sensor 2nd Gen Flush Mount (sensor).


**Printing advice:**
Rotate the mesh on your print bed so that its laid like a hat and you won't need any supports.

**Scaling**
The mesh is sized to fit the Ring Alarm Contact Sensor 2nd Gen, with room for a ribbon behind the sensor to facilitate removal. At 100% scale, it's designed to be gravity assisted and hold the sensor in the top of a door. You can scale it down up to 1mm less on the longest side for a very flush fit, in which case it will mount in any orientation.

If your printer isn't calibrated well, I recommend leaving it at this size, or stopping the print after the first 10 layers and seeing if you can push your sensor through the hole.

**Install**
Per above, I recommend threading a ribbon under the sensor, so that you can easily remove the contact sensor to change batteries. If you have a flush fit and no ribbon, I've included a finger hole in the base that lets you poke the contact sensor out, but
