I have a number of long Irwin "Quick Grip" clamps for my woodworking, but the rubber covers seem to like to go missing. I couldn't find anything on here and thought that it was an opportunity to play with OpenSCAD.

This is my first design, and after half a dozen tweaks, fits exactly the same as the original covers. It needs a firm press to fit to the clamp (being PLA and not rubber) but it goes in with a satisfying click.

I've no idea about longevity, but it only takes half an hour to print.

OpenSCAD file included if any adjustments are needed. My clamp opens to just over 12" (32cm) between the jaws, I don't have any of the 6" ones so don't know if the business end is the same.
