Brass Heat-Set Insert For Printed Blasters (M3)

You know them, you love them, it's the standard heat set insert used for many of the hobby's current 3D printed blaster offerings. With a M3x0.5 threading these are super easy to use with off the shelf hardware.

These inserts use a 6.4mm deep 5.5-5.6mm diameter hole with a 4 degree taper.
