Pringles Honest John

thingiverse

This is a not quite to scale version of the Honest John military rocket of the 50s using two Pringles cans for rocket tubes. The base used the taller "Party Stack" tube while the top uses any regular sized Pringles tube. This is a HEAVY rocket and should only fly on an E or above using a short delay. But it's pretty neat to see fly. It screams on a composite E-30 or above. Most parts can be printed without supports, but the fins you will need supports for. I printed them as they sit. You'll need a shock cord and 30" chute, but not much else to make your own (and if you do, please post a make). Yo udo NOT need a motor tube for this rocket as it's built into the 3D parts. 7/27/2021 Update: Changed the motor retainer to make it look a little more like an engine bell (and also make it more robust) and added an Aerotech specific retainer which has an extra 4mm space for the Aerotech retainer rings. Also added a "RetainerHolder" which is an optional part that can be glued to the base of the nosecone to hold a spare, or alternate motor retainer just in case you need one, or are switching between Estes and Aerotech motors.
