BT-55 Fin Can/Retainer with Nosecone

cults3d

Wanted to make a lightweight fin can for BT-55 body tubes. It accomodates 24mm motors (D and E). The fincan has 5 fins around it, all attached to an outer ring. attached this to an 18" BT-55 body tube along with the nose cone provided and the rocket flew stable, quite high, even with a D motor. I will probably put the 18-24mm adapter on some C motors when flying this in more constrained areas. The nose cone has a solid tip, and since the images i provided were from a clear blue resin, you can also see 3 rings inside of the nose cone for a bit of extra rigidity. Its been a fun little project, easy to print. The nose cone i printed directly on my build plate without any supports, same with the retainer but the fin can itself required me to use some supports.
