I wanted a screwdriver to keep in my camera bag with all of the relevant bits for my camera and equipment. I wanted it to be short enough to fit into a particular pocket on my bag, yet have storage for all of its accessories. The handle is long enough to store a bit extender as well as the bits I chose to use a PET soda bottle cap to contain it all because it's a proven design and if I lose it, a replacement is as close as the cooler in my car.
Printed vertically with the bit end on top. Since this is a tall, narrow print, you will need a raft or brim to keep it from falling over.
I used PETG because I don't have the same confidence in the strength of PLA and I didn't want it to warp if I left it in a hot car on a summer day. However, your experiences may differ from mine.
A small neodymium magnet is epoxied into the handle to hold the bit extender in place.
