small hex bit holder
thingiverse
Open up the picture to see what's going on. I've got one of those teeny electric screwdrivers that uses miniature hex bits, and I think you can find them at Wal Mart for ten bucks. The hex bits measure about 4mm in diameter across their flats. I whipped up a little tool holder to stash the bits and the screwdriver, and clipped it onto the edge of a wire shelf. I added a 0.5mm brim to keep the back leg stable during printing - I'm a big fan of custom brims, by the way. Just remember to cut that off post-print.
