UPDATED 2047 2023-0210 MST if you downloaded before then download it again. Nose cone was too lose I tightened it up a little (have not reprinted yet) and the shock cord mount printed "closed" this has been corrected. Bodacious Jaban-Lappi Tinkercad Flying Rocket Someone pointed out that Tinkercad had a "rocket" as one of its premade models (under vehicles) I said oh no can't let that pass have to make that flyable. SO here is that design in flyable form (untested !!! might need some nose weight) designed to fit on a printer with 250mm z like an ender 3. Since its the tinkercad rocket I let Tinkercad name it :-) the whole thing prints in 2 pieces in VASE mode. to finish you will need an 18mm Motor tube (have not tested fit will test that soon) to go up the center to about 3/4 the way to the top glue that in and your preferred method of retention. tie about 5ft of thin kevlar cord to the small attachment point INSIDE the tube tie the other end to the nose cone. tie your streamer or very small parachute about 75% the way to the nose cone on the kevlar cord. the plastic parts only weigh around 50g or so plus the mass of the Motor tube engine and recovery system. It might need a little nose weight. The nose should fit smooth but NOT TIGHT. ie easily remove but not falling out if you hold it upside down and gently shake. if its too loose add a tiny bit of tape to the shoulder to tighten up the fit a little. launch lugs are 1/4" so it can fly from any normal 1/8" 3/16" or 1/4" launch rod. I bet a 1/2A6-2 would be a nice motor for this. I may redesign for 13mm motors.
