Mod-IO Olimex enclosure

This is a Olimex MOD-IO enclosure, quite stackable. I designed it in short time so Freecad source is not very clean ad still in progress. My top cover is higher than necessaty in order to host additional PCB or protoboard. I used it mounted on din rail by OK1HR and John Cabrer OpenSCAD DIN rail clip

Top cover needs support in printing, in corners, where screw hole are.
