When the original NuTone intercom doorbell at my house stopped working, I decided to reuse the existing wiring and upgrade it to a modern Ring wired doorbell.

The challenge was the giant, oddly shaped opening left behind by the old intercom. Instead of patching the stone or removing the old mounting location, I designed a custom 3D printed cover plate that keeps the look of the original while giving it a clean home for a modern smart doorbell.

This was printed in PLA as a quick solution, and surprisingly it has held up for over a year. The installation is partially protected from direct rain and sunlight, which has helped, I’m sure.

Features:

  • Replacement cover plate for a classic NuTone-style doorbell/intercom

  • Designed to fit a Ring wired doorbell

  • Reuses existing doorbell wiring

  • Mounts in the original intercom location

  • No wall modification required

  • Simple print-and-install retrofit

Print settings:

  • Material: PLA (PETG recommended for fully exposed installations)

  • Layer height: 0.2 mm

  • 4+ walls recommended

  • Supports: none
