Thanks. I'd like to try to get one before trying to print it. I'd probably use PETG if I did print it.Here are the files to print one: https://www.thingiverse.com/thing:6384202
Waiting on the website to respond. Running sloooow...You can get one directly from Estes.

Sadly Estes 3" tubing is 3" OD, not 3" ID like high power tubing, so an Alpha built on Estes 3" parts cannot accommodate a 75mm motor.I fiberglassed a standard Alpha, and flew it on 24mm F's... the 3" version should do well on 75mm M's

I made mine from the GM kit but used the Big Daddy NC like shown in the photo (ala Duffy).

It’s lawn darted several times and is 3in shorter so far. The NC has survived so far.
I belatedly realized I should have asked Galactic Mfg. to make it a 38mm motor mount option, as I would love to fly it with Loki G70s.Where did you get the fins for a 3" Alpha? Thought about doing one myself. I have a BT-80 3x24mm cluster version and love it. Would like to do a 3" single 29mm version.
Eh, maybe, maybe not. I'd rather buy some 38mm CRs and trim the tabs. Trying to ensure I'm on-center when enlarging rings from 29mm to 38mm is a bit iffy.Just open up the CR, add a 38mm tube, trim the fin tabs, and good to go!
Just pulled the trigger on the PNC300 from BMS.BMS sells two 3-inch nose cones for their T-300 airframe: an 11-inch ogive and a 4.3-inch elliptical.
Their T-300 tube is 3.00 inch OD / 2.93 inch ID.
The 11-inch ogive is a real beauty !
I wonder if either of those would fit your tube and your model ?

EDIT: oops ! what @SolarYellow said !
Got one going through customer service a few months ago.I have plenty of 3" Soller Composites fiberglass sleeve...
As others have noted, Estes does not sell it separately on their website. I'm considering buying a BD for the NC. Maybe even a Doorknob.
Got one coming.Got one going through customer service a few months ago.
Meh. I'll go with what I've ordered.
That's a nice non-V2 rocket.Behold: A 3" Alpha using the BMS cone. Through-the-wall fins with 1/8" ply core and 3/32" balsa skins for 29mm power. Nose cone since painted red.
A second cone is slated for an Up-Rated Alpha from Estes TR-11 tech report that will require carbon fiber fin skins.
