About this 3D model
For those mounting LED strips to your Prusa i3 Mk2, here's a box allowing you to mount a switch for it. I used the following miniature rocker switch from McMaster-Carr: https://www.mcmaster.com/#7395k28/=161m8js The box is designed to hold that specific switch, but others with similar dimensions will probably work. Also uses 3 M3x10 screws to hold the lid in place. You may need to push a little to get the screws in, but they will go in. Once you have it together, you can mount it to your aluminum frame (I put mine just above the PSU, mounted with double-sided mounting tape).
