Ring Doorbell Pro, 1/4 inch spacer backplate

thingiverse

My Ring Pro (hardwired) doorbell started malfunctioning intermittently before completely shutting down. It was initially installed as a retrofit replacement for an existing doorbell using existing 1987 wiring within a brick veneer home. The root cause of this issue turned out to be a broken wire, which I couldn't pull any further due to the confined space behind the doorbell. Consequently, I had to splice in a short piece of wire utilizing a snap lock telephone wire connector. The real challenge lay in fitting all these components snugly behind the doorbell and into the mortar-filled hole without attempting to chisel or drill it out and risk cracking a brick at the front door. To resolve this issue, I needed additional space behind the doorbell. My solution involved searching Thingiverse for an existing design that addressed similar problems. Upon discovering many designs ranging from sun shades to angled mounts for ship lap siding, among others, I decided to use dstasiak's excellent design as a starting point and modify it to suit my needs. I adjusted the thickness of the spacer to 1/4 inch and customized the screw mounting hole spacing to work seamlessly with my Ring Pro at 105mm. Since I was altering the thickness, I also made some additional changes to improve its functionality: * The opening for the wires was enlarged to accommodate varying levels of hole penetration into the house relative to the mounting holes. * The outside corners were rounded for a more polished appearance. * The ribs were thickened to 1.2 mm to ensure compatibility with a 0.4 mm extruder. * The 90-degree intersections on the back side were rounded for aesthetic purposes. * Drain holes were added to the bottom edge in case of rain or condensation accumulation behind the spacer. * UP ARROWS were incorporated onto the back side to indicate the correct mounting orientation. * The shape of the screw hold openings was modified from oval to racetrack. I successfully printed one unit, and it is functioning perfectly. If you require a thicker version, you can either modify the STP file or scale the STL in the front-to-back dimension for a simpler solution.
