Primrose Model Rocket (18mm motors)
thingiverse
A simple 18mm model rocket, easy to print (supports required, brim recommended). Comes in 3 sections, Fin can/Motor tube, Main body, and Nose cone. I recommend using 45cm Estes parachute and shock cord, and an Estes B6-2 motor, although it can fly with almost any 18mm motor available. I found that plumbers tape (really thin Teflon) seals the joint between the body tube and the fin can pretty well. Compatible with 2-2.5mm launch rails. (also included is a nose-mounted Benchy for fun, completely untested and probably flips around)
