Universal Tool Handle
thingiverse
You can adapt this design to fit your Pittsburgh ratchet, but it will also work well on other hand tools like files or screwdrivers. To use it, just cut out the desired shaft hole in the handle. If you'd like, feel free to share photos of your printed handles. UPDATE 7/9/2018 I've added a step file and an .f3d version of the design for those who use Fusion 360.
