Raspberry Pi B+ Bumper

Summary I haven't found a case I like yet, so I thought I'd make my own bumper cuz I quite like seeing all the technical bits, and still having access to everything, but wanting the safety factor on knowing that I can put it down on the metal ruler without a meltdown. This fits the B+ model only, and the base has pins that poke through the screw fixings. The top friction fits over the pins.
