Replacement spring for Duratech pliers

thingiverse

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). Your mileage may vary.
