About this 3D model

Put your project in an Altoids case. This has blocks that hold the PCB and can be "melted" with a soldering iron or similar to keep the PCB in place. Also, there are 2mm holes that can be drilled out to your preference to use screws to hold the PCB in place. There is 3 mm of space under the PCB, ample room for wires and leads underneath. Radio Shack still sells a general purpose PCB (part #276-150 http://www.radioshack.com/product/index.jsp?productId=2102845 ) that is very useful and for which I have designed an Arduino compatible circuit. The PCB has 417 holes, so the design has been dubbed "417duino" (although I regret not calling it 4-seventeeno) Access for FTDI programming, power, or other connections may necessitate holes through the Altoids tin, but I leave that as an exercise for you, gentle maker.
