The Rotolatch™ system was originally designed to be easily injection molded. Our cost-optimized latch design is a two-piece assembly. We have not invested in molds because our 3D printed PETG parts work just fine. Rest assured, our injection-molded part design was created by an experienced plastics designer and licensed professional engineer. We expect an injection molded system to be smaller (due to reduced friction) and more reliable than our 3D printed parts.
