This is a box for 60 (magnetic) hex screwdriver bits, an extension bit and a (also printed) stubby screwdriver handle. Hinges on the box need an iron wire or something to put together. The place for stubby screwdriver handle was designer for http://www.thingiverse.com/thing:50365Should be printed with a very low fill ratio as the box is pretty chunky. Slot for hex bits are also quite tight, so if your prints tend to shrink, scale this model up first. Better safe then sorry.
