Warning: not 100% complete
A Screwdriver based on the "Balisong" (Butterfly Knive) design (two independent movable handle sides). It has a 7mm hexagon front that most drill bits should fit into.
I took the overall shape from a cheapo "Keen Blades" Butterfly knive.
It seems I miscalculated something with the front piece, it won't fit between the handles, and the screwdriver won't latch closed, because the handles are too far apart. Also the front is a bit too big to properly accept bits. Last the bolts aren't going to work nicely.
I will retouch this design soon.
Just print everything once (except bolts). You can try them if you want (3 of them) but I doubt they will work.
