Update: Flew this on Easter Sunday and it flew like a dream.  I used a B6-6 and it seamed under powered.  Next flight, will be on a C6-5.       SEND IT!!!

These are parts I designed to upgrade my Estes Black Brant kit.  These were printed in PETG 0.2 layer height, 25% infill, and optional supports on the nosecone shoulder.

• Nosecone - fairly accurate replacement with a  threaded shoulder for the ebay cap
• Ebay Cap - threads onto the shoulder of the nosecone with vent holes.  Stuff your Estes altimeter in there
• Ebay Ring - you can use this to convert your existing Estes nosecone into an ebay
• Fin - print this flat for strength, upright to maintain the airfoil shape
• Centering Rings - simple replacement rings with a small hole to allow for a Kevlar shock cord 
• Retainer Ring and Cap - I never use motor clips.  You can sub out the tail cone for this.  They don't look as nice but they are nicer than clips.  Use them for something else.
