Double sided wrench

Customize the size of both sides of the wrench.
Remember to use the insert size of the nut instead of the outer nut size.

I have updated the wrech a little bit so it will be a little more thicker on the outside.
I have printed it with a 20% infill and noticed that the PLA is bending a bit, but is gives enough tension to lock the nut.
For a better functionality of the wrench you have to increase the infill density.
