About this 3D model

This is a remix of elcarlos's nice Historical Wrench with modifications to make it more easily 3D printable. I liked the original design, but felt that the supports required on the handle could be eliminated with a few changes. Large chamfers were added to the handle to avoid flat overhangs and the Knob and Top (jaw) were also chamfered to match the handle. The resulting design is very easy to print with no supports required. The threads have been clearanced to work smoothly at 0.2mm layer height.
