Small Letter - Envelope Opener (Circle, Heart & Square Shaped Handles)

These are simple, small, easy to print letter/envelope openers with circle, heart & square shaped handles. At only 2mm thick, they use minimal filament, even when printed at 100% infill (2.44g, 2.34g, & 2.53g respectively). I printed mine in white PETG, with 100% infill, at a 0.12 layer height. These function similar to most knife style openers.

I wanted a heart shaped one for a specific purpose, and then I made the other two shapes just for variety. They work well. WARNING: the tips are rounded, but they are still fairly pointy (protect your eyes). Also, the blade edges are relatively sharp, so keep them out of the reach of children (and careless adults). The cut that one could receive from these is similar to a paper cut. All three blades are the same, with the variations being in the handle shapes. The designs are ~80mm long x 30-35mm wide.
