Katana 3-gang Decora light switch cover

A cover for 3-gang Decora-style light switches, inspired by katanas and traditional East Asian motifs. No MMU or AMS needed.

Required Hardware:

• 8x Round magnets (6x2mm)

• Round double-sided tape (usually 10mm / 1cm diameter)

• Superglue

Assembly Instructions:

1. Use superglue to attach the handle wrap and handle end to the handle base.

2. Use double-sided tape to attach the blade to the rocker. See the image for the correct assembly order and orientation.

3. Use superglue to stick the magnets to the magnet holders.

4. Attach round double-sided tape to the back of magnet holder #2 (See image).

5. Press the case against the original cover. Magnet holder #2 should stay on the original cover, leaving the case completely removable.

6. Attach the fully assembled handle to the blade.

All files are pre-oriented for the best printing results and structural strength. Add supports as needed, depending on your setup.

(Note: I am currently travelling, so the main image is a 3D render. Real photos of the printed model will be uploaded as soon as I am back!)

Update July 13: I uploaded a new version of the blades. No design changes were made, but I increased the contact area with the build plate to improve adhesion. If you downloaded the previous version, simply lower it by 1-2 mm on the y-axis.  

Update July 14: I test-printed the case and found that some small brush strokes were difficult to print. So I smoothened some details.
