BT-50 to BT-20 Boat Tail / Tail Cone
 
This is a 3D model of a boat tail / tail cone for rockets meant to fit BT-50 airframe tubing.

This is modeled closely for the Estes Sprint (kit# K-49/#1249).

There are two versions - one that is plain and one with a tunnel to allow for a motor retainer clip.

Nice! I was never very good at paper transitions.

I did some test prints and found there were some problems with the design. I re-designed one, test printed it, made more corrections, and finally came out with a print I liked. I re-designed the rest and added a few more versions.
