Using these to thread connecting points that need regular removal. way better than the 3D printed threads I was using. Super durable. Just heat set with a soldering iron and off ya go.Hot tip, thread your fastener in so its flush with the bottom and push it in that way. Keeps plastic out of the internal threads.
