Longshot Stripper Breech

I was boring out my Longshot breech, holding it by the sled attachment point, when the breech snapped away from the sled and the tooth. I have no intention on removing the breech from the bit anytime soon. And I was ticked. So I ragequit. Then my math teacher offered to print one for me. so I went on to rageCAD (that's a verb). And this is what came out.

I have never transcribed a part faster in my life.

The only parameter that has not been made to spec is the length of the tube.

grrrr
