Threaded insert M3 (10pcs)

A set of 10 threaded inserts for plastic. These inserts are very practical when you need to create a thread in a 3D-printed part to attach it to a frame. The inserts have an M3 thread and are available in lengths of 3mm or 4mm (depending on the variant). To use them, heat a soldering iron tip to around 270°C and melt the insert into a prepared hole in the 3D print (a suitable hole diameter is 4.2-4.3mm).
