The Mmintbox is my design for an enclosure for an Arduino with an LCD keypad shield. These are the files for my latest prototype. It was the subject of an unsuccessful Indiegogo campaign to make an injection-molded version. EDIT 2014-08-01: Added the Solidworks 2013 source files, as well as STEP files for each configuration. CC-BY-SA, so have at it! If you make molded ones, send me some, k?This version of the case will work with LCD keypad shields from DFRobot, Sainsmart, and most of the generic ones from eBay. The case has supports built in to handle the overhangs, so no support material is necessary. I used the button mold to make button pads from Oogoo: http://www.instructables.com/id/How-To-Make-Your-Own-Sugru-Substitute/
