Designed for 14 mm long pins, though 12 mm will also work. The pins can be hammered into the print or pressed in using a vise or a press. I have made versions for pins of 2, 3, 4 and 5 mm diameter. The wrench is slightly flexible to change the pin spacing. The following are the default values, but they can be easily adjusted in the Fusion 360 file:

Pin Diameter Pin Center-to-Center Distance as-printedPin Center-to-Center Distance Range
2 mm8 mm6 - 13 mm
3 mm12 mm9 - 21 mm
4 mm15 mm13 - 43 mm
5 mm20 mm16 - 51 mm

 

Adjust the number of perimeters such that there is no infill around the pin, otherwise the wrench will not have enough strength:
