Handle for Allen/Hex Wrench/Key

thingiverse

The original handle for hex wrenches found at http://www.thingiverse.com/thing:129760 was limited to a single size; however, now there's a customizable version available! Simply measure your key's widest point and input the measurement as the hole diameter in the customizer. The slot dimensions have been increased by 0.15mm for printing variances, but you can adjust it. Additionally, feel free to alter the handle's diameter, with a default size of 25mm.
