1/4" hex bit holders

thingiverse

I found myself in need of some 5 lobe tamper proof bits. The set that I settled on didn't have a holder, just 7 loose bits. I created these to solve the problem. Simple design, and economical. The walls and floor are all 1 mm thick, so they print fast, and use very little filament. I used Sketchup Make 2017.
