I added a laser etcher to my Ender 3 Pro, and I didn't want to have to keep plugging in and unplugging the laser on the main board, so I created this switch.

I used this box ( https://www.thingiverse.com/thing:4441076), and added the front panel with 5 color changes.

Your firmware needs to support the M600 command to print this easily.

I used Tinkercad, and made each area I wanted the color changed on slightly higher than the previous area

I then used PrusaSlicer and placed a M600 color change at each color change level.
