I have too many of these small screwdrivers that vendors include with their wares, however I can't bear to throw them out - it seems so wasteful. So instead, I made a small storage block to hold a bunch of them. This can likely be used for precision screwdrivers as well that have a shaft with diameter of less than 4mm.
Of course, if you find you have significantly more screwdrivers than I, then you can use the Onshape document to tweak the parameters to your own liking, or if you're stuck living in the past, there is a .STEP file for you.
Coarser presets give a nice, stepped pattern on the top face, or you can choose to print it with the holes on the build plate for a smooth surface.
