About this 3D model
I installed an integrated PSU in my prusa and wanted a convenient power switch handy. I purchased the LED switch from amazon (http://www.amazon.com/gp/product/B001TPXUN4/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1) but I included the openSCAD so you can easily change it to any button size you get.
