Threaded inserts by CNC Kitchen, community creator and youtuber. Threaded inserts not only look great in 3D printed parts, but they also have a practical use. Everyone has had a de vice that was assembled with screws. After disassembling and reassembling it a few times, you realize that if the screws dug directly into the plastic, they won't hold anymore. Each time you screw the parts together, the material gets plastically deformed at the threads, which eventually leaves you with nothing but a ragged hole where nothing can grab. This is where thread inserts come into play. By melting them into your parts, they are positively bonded to the plastic and no longer move. The screws are now turned into durable and also low-friction brass and thus will last forever. Show more
