Faucet Sensor Hack

thingiverse

Inside diameter: 55.5mm I created this ring for my American Standard Selectronic faucet, allowing me to set it down around the base of the faucet on the counter. It freely rotates to cover and uncover the sensor unit. I initially made this so that I could keep the faucet running when needed. Here's the interesting lesson I learned during this project: if you print the tool in a dark color (I tested black ABS and chocolate brown PLA), the faucet will not trigger, instead blocking off the sensor. On the other hand, printing with a light color triggers the sensor. I've got a simple print-in-place model that you can print in either dark or light colors. The cuts into the model indicate running water, but do with it as you please. The MMU models can be printed in various colors. My intention was to have dark material on the "X" side and light material on the water side. Now you have a single tool ring that can either lock out the sensor or activate it. Happy making!
