This is a 3D model of the Estes BNC-50BC nose cone. It is designed to fit Estes BT-50 airframe tubing.
Do not confuse this nose cone for the Estes PNC-55D which you can find here from another designer.
There are five files you can download. There are two versions of the nose cone itself (with and without the shoulder) and the other is the end cap which has a 3mm hole in it to allow you to add a screw eye or eye bolt.
The second version is designed to look more like it has a ramjet intake.
