My first injection mold and the Rabit HY-4 injection molder

[gavztheouch]

the taper that opens out the hole has an included angle of 30 deg so you need an engraving tool that size,

I think the 30 degree taper is not part of the mold but instead part of the machine that injects the plastic. My thoughts are this is a heated tip and the plastic will flow around this?

That makes it relatively easy to make then, carry on number one.
