Printing with no supports. This is a wall plate adapter when replacing a Google Nest with a Honeywell T-5 Programable thermostat. It is designed to cover the same area as the Nest wallplate and screws into an existing electric box while covering a large hole in the wall. It requires you to also pick up 3 #2 ½" nuts/bolts for the UMP-16 and two #2 bolts for the mouting to the electric box mounting holes.
