In a need to hold larger screwdrivers on my workbench, I made a simple design that can easily accommodate the handles from larger screwdrivers and even the multi-bit / multi-driver / multi-purpose screwdrivers that just about everyone has at this point sitting in a tool bag someplace.

I am only publishing my second iteration with the slightly larger holes as the wider blade screwdrivers would get jammed up on my initial design.
