Bedside Lamp Switch Retrofit Base

• Structural Design The entire housing is designed as a single-piece structure, with custom internal retaining slots tailored specifically for the single-gang switch module shown in the diagram. M3 threaded posts are provided at the four corners to secure the cover plate, while side openings accommodate wiring routing. This surface-mount design eliminates the need for pre-installed wall boxes; mounting holes on the exterior allow direct adhesion or screw fixation to walls or bedside panels. No supports are required during printing, and the part is produced in one piece. An exclusive logo is engraved on the outer surface for high辨识度.

  

• Compatibility and Installation Features The internal slot precisely matches the standard 86-type single-gang switch module illustrated. Once inserted from above, the switch locks into place without any wobbling. This surface-mount design lowers the barrier to modification—no wall chiseling or grooving is needed—and enables easy disassembly and reinstallation. Ample cable-routing space within the base prevents wire compression and potential short circuits. With 3D printing, users can freely choose filament colors to match their home décor. The shell’s moderate thickness ensures structural integrity and resistance to deformation.

  

  

• Usage and Practical Value This solution addresses the common issue of lacking pre-installed junction boxes in bedside areas, enabling external wiring and surface-mounted switch installations. It also provides an excellent opportunity to practice designing electrical enclosures, retaining slots, threaded posts, and other functional structures. The finished 3D-printed component can be directly applied to minor home circuit modifications, making it ideal for electronics enthusiasts and DIY home improvement aficionados—offering both practical utility and valuable hands-on experience in modeling and additive manufacturing.
