In this video, I put a theory to the test: using a hot glue gun and 3D printed molds for DIY injection molding. Armed with PETG molds, vegetable oil as lubrication (because why not?), and a budget-friendly hot glue gun, I aimed to create waterproof repairs and protective coatings for wires. Join me as I walk you through the process, share my findings, and demonstrate how this simple setup can produce excellent results. Perfect for quick fixes and creative solutions!
