WERA Kraftform Micro Handgrip

This is a handgrip which fits over the hexagonal section of the Wera Kraftform Micro series screwdrivers.
There are two versions, one which will suit most of the smaller size shafts and one which should suit the larger diameter shafts.
I made this using cubify invent and have included the source files.
The fit over the hexagonal section turned out quite well on my printer, (which usually prints a little oversized) so Im confident the screwdriver should fits without needing to file/sand any
