This bracket holds a Mintyboost from Adafruit in place of the bulb assembly in a 3-D cell Maglite Flashlight.

The Mintyboost from Adafruit is an excellent battery powered USB charger circuit. It was designed to use 2 AA cells and be housed in a mini altoid tin container. I was looking for significantly higher capacity and a rugged housing, and stumbled over my 3D cell aluminum Maglite. Removing the bulb and reflector, I created a space to hold the mintyboost board. By disassembling (breaking) a bulb, power can be drawn from the bulb socket.
I sliced it in Makerware, medium quality (.27 layers, 2 shells, 0% infill). It sticks to the plate like glue -- take your time and a nice spudger to get it off...
