I wanted to put my hex precision screwdrivers on the Multiboard but no holder would do the job so I designed my own.
It fastens with two 9 mm small thread flat head bolts. The middle hole is not used but it's there if you want a single holder; just split the step file into objects and print the middle one.
Print as you would any other Multiboard accessories and flat on it's back. No supports needed.
