About this 3D model

Replacement Hand Crank for a "B&D Workmate" early model. My workmate was bought in the 1980's and is almost 100% metal with a wood top. It is similar to the Black & Decker 21321 model or WM425. The swivel-clamp-pegs and the hand cranks are plastic. One of my hand cranks broke and epoxy didn't fix it so I took the measurements and designed a replacement. The replacement I designed now has a double handle but it's easy to delete the second crank from the OpenScad file if you want it more like the original. I believe the double crank will give better leverage to really tighten the clamp and loosen it again. I also thickened up the crank and head quite a bit, and added some reinforcement since a printed part isn't as durable as a molded part. The critical dimensions should be the same. The angles are changed to make it easier to print but that shouldn't matter much.
