This is just a basic switch bracket that attaches to the top of a Monoprice Maker Select V2 control box. I used it to control my LED lights (for a full write-up, see http://levihefner.com/my-projects/2016/12/8/adding-led-lights-to-monoprice-maker-select-3d-printer). Feel free to make it better! And if you use it, be sure to share a photo!
