It can be really tricky to screw something together when you don't have enough space to hold the nut with your finger in position. So I added support for a cap on the closed side of the wrench which can be used to hold a nut in position while screwing.
This wrench is a derivate of gr0bs customizable wrench (http://www.thingiverse.com/thing:47842).
Also includes some minor enhancements:
- deeper engraving
- kerf size tightened
- lowered text height
