PNC-50K Nose Cone (BT-50 and BT-80 versions)
It's time for another 3D creation by Hydrazine Design!
This one is the Estes PNC-50K nose cone most famously used in the Alpha III model kit. Estes kits that use this nose cone: K-56 Alpha III 0650 Quasar 1256 Alpha III 1258 Alpha IV 1989 Liberty There are two designs with one fitting BT-50 tubing and the other BT-80 tubing. You can download them for free from Thingiverse and print them on your 3D printer. https://www.thingiverse.com/thing:6289096 |

Additional places this nose cone has appeared since John Brohm updated his list: Alpha VI (pink metallic), the unnamed rocket in the Rocket Science Starter Set (black, like Alpha IV). And, molded in clear, most versions, including the current one, of the Phantom. I think Mr. Brohm’s list has the clear one as a different part number….but they are physically interchangeable.
There was also a period of about three years centered around 1991 where the regular 1225 Alpha could come with either a red or — rarely — a blue one as an option to a blow-molded white nose cone in either the older shape or the current one. Yeah, I know, minutiae. But the red (original Alpha III) and orange (Alpha III since 1993) are the major uses of this unusual injection-molded nose cone. Jack — does your version have the boss on the inside to used to attach the small screw eye? A quick look at the info on Thingiverse leads me to think it does not. If it doesn’t how do you suggest one attach the shock cord/‘chute to it?

I didn't know they had been manufactured in so many different colors. Love that minutiae!
My nose cone does not have that spot for the screw eye. |

The images on Thingiverse make the tip look considerably more conical than the injection-molded part, which is as close as I can tell spherically blunted.

Yes, I screwed up a little on the shape and took the old files down and uploaded new ones that look much better. |
