Busch-Jaeger Reflex Supportless plates: 1-2-3-way

I recently worked on something that I’m really happy with and would love to share: a set of 3D-printable cover plates for Busch Jaeger Reflex switches. My goal was to create an efficient, supportless design that’s easy to print, looks great, and solves a few challenges I came across with other models.

Why I Made This

At home, we have a lot of smart lights that I don’t want to accidentally power off. While searching for existing cover plate models, I noticed that none fit perfectly, especially for a 3-way switch. Many designs also required supports, which felt like an unnecessary use of material. So, I decided to create my own models for 1-way, 2-way, and 3-way switches.

Key Features

• Supportless Design: Each model includes tiny, built-in supports that are easy to remove with less than a gram of waste. This keeps the print material-efficient while maintaining quality.

• Multi-Switch Compatibility: Designed specifically for 1-way, 2-way, and 3-way switches.

• Lightweight & Press-Fit: These plates fit snugly using the metal clips that come with the Busch Jaeger Reflex switches—no extra fasteners needed.

• Material Optimized: Created for 0.6mm nozzles and prints beautifully in Wood PLA.

• Quick Print Time: Approximately 35 minutes for the 1-way switch and just over an hour for the 3-way switch.

Printing Tips

• Printer: I used a 0.6mm nozzle on my Bambulab A1

• Materials: Wood PLA works wonderfully if you like a natural look. - Included file is set to Bambulab PLA

• Files: Includes STL files, printer profiles, and a Fusion 360 file for those who want to customize or improve the design. (The Fusion 360 file is a bit messy—good luck!)

Design Improvements

The initial version didn’t account for wall protrusions, so I updated the design to include a small clearance for the metal sockets that stick out about a millimeter. This ensures a better fit while avoiding floating gaps, supported by the tiny, built-in supports.

Why I’m Sharing This

This isn’t about claiming it’s the best solution—it’s just something that I enjoyed creating and wanted to share. It’s a design that’s efficient, functional, and aesthetically pleasing (especially in Wood PLA), and I hope it can be useful or inspiring to others.
