This page is where you will find any 3D print (.stl) and Laser Cut (.svg) files as well as building instructions and a bill of materials with links to all the parts and tools needed to build a SimpleSolar SolarBox MK2 unit. While we recommend a 3D printed case, it isn't necessary to own a 3D printer, there are services that you can pay to do it for you if you send the files to them and some libraries now have 3D printers. Also, as some people may have figured out themselves, there are other ways of making a good looking box with three holes in it.
