Printed on Rep 2 Infill 0% Shells = 3 or 4 depending on the thickness you want. Old school. Break to open... No raft No support Added a second STL, with a flat spot and bridging design around the coin slot, as I had some trouble printing the coin slot. I think this would be very slicer dependent, I see the new makerware seems to want to use diagonal fills instead of horizontal - and that leaves a little clean up on the finished part around the coin slot. Would be interested in other slicer results...
