A simple custom decorative frame for Legrand Niloe / Niloé-style single-gang wall switches.

I designed this frame after measuring an installed switch mechanism and tested it on the switch shown in the photos. It replaces the visible outer decorative frame and lets you print the part in any color you like.

The model is approximately 85 × 85 mm outside, making it a practical replacement-style frame for common 86 × 86 mm Niloe faceplates. It has rounded corners, a clean square opening for the rocker, and small snap/retention features on the back.

Files included:

- STL

- 3MF

Suggested use:

- replacing a missing or broken decorative frame

- color-matching a switch to the room

- printing custom decorative switch frames

- experimenting with different filaments and finishes

Compatibility:

Designed for Legrand Niloe / Niloé Step style single-gang switch mechanisms with the large square rocker.

This is an unofficial compatible part. It is not an original Legrand product and is not guaranteed to fit Valena, Vimar, Gewiss, Schneider, Bticino, or other switch systems.

Printing:

Print flat. No supports should be needed in most slicers. PLA is fine for normal indoor use; PETG is a good option if you want a tougher part.

Safety:

This is a decorative plastic cover only, not an electrical component. Turn off power before removing or installing parts around a wall switch.
