WRENCH

A very simple wrench, but since it is to be 3D printed in plastic it may only have a few uses before it wears so here's some tips. Wrenches undergo a lot of stresses and tensions and friction can cause the plastic to start rubbing off and lose its integrity. if using STL, print with a very high infill density, but ABS is much more reliable and does not require such a high infill. This wrench was modeled for a 1/2 and 5/8 diameter hex nut but I provided the drawing dimensions so that you can create your own for different sized nuts through scale factors. If you have any questions or improvement recommendations let me know.
An inch and a mm version is provided.
