Contact Sensor offset designed to fit into a  Ring gen 2 contact sensor. Offers about 9mm worth of offset so that it would fit onto my sliding door like I wanted. Fits snuggly into the sensor housing and the small tip is big enough to keep the tamper switch depressed. 

Printing and prototyping done on an Ender 3 w/ 0.6mm nozzle and matchbox PLA.
