Replacement spring for Duratech pliers

These cheap pliers are quite good, especially for removing support material. However the spring doesn't generally last more than a few months of solid use. Having broken a spring 1 week outside the warranty period, I designed my own. This should be printed in polycarbonate, but ABS may suffice. I've also included a version with much larger radii for use with brittle plastics. That version won't spring as well as the polycarbonate (which feels just like the original stainless spring).
