Set of threaded inserts for plastic M2/M3

M2 and M3 threaded insert set for plastic. These inserts are highly practical when you need to add threads to 3D printed parts for mounting the print to a frame. The set includes a total of 500 inserts in various lengths. To install, simply heat the insert with a soldering iron tip to around 220–270°C (depending on the material) and melt it into a prepared hole in the 3D print.
