Just a super simple design, posting mostly for inspiration then to save you time designing it, but I have had this double sided taped to a shelf above my bench for probably more then a year and it makes it super easy to grab the right screwdriver when I need it without taking up space and getting in the way.
This one in particular is designed for a set of 4 Wiha screwdrivers I have so feel free to modify the hole geometry to fit your set of screwdrivers.
