The new Modifi3D PRO tips are not compatible with the original Modifi3D. The improved construction is very different with the heating element being separate from the actual tips.
The insert setting tip works with M3, M4, M5 and M6 threaded inserts. It is designed to fit the minor diameter of M3 and M5 but also functions with M4 and M6 due the flat surface on the tip steps.
