I modeled this wrench holder to hold my set of 10-19mm GearWrench Crowfoot Wrenches. It is based on an existing design from Thingiverse, but re-modeled to fit the GearWrench set as well as for easier printing.
Tolerances are pretty tight as I didn't want them to rattle or flop around. I'd recommend ensuring your printer can accurately recreate an interior hole to ±0.1mm or better.
