Good evening! Here is my most recent project. A 1/15 scale V2 that I drew up in CAD and is nearly entirely 3d printed (fins are laser cut ply.) I haven't flown rockets much since I was a kid but started this year (at 45) as an Industrial Tech teacher at a High School where I currently teach various CAD courses, Engineering, and Robotics. To get the kids from design (Inventor) to testing; I set up a project where students had to fully design, print, build, and fly model rockets. This V2 is my scaled up nuttiness to inspire them as they worked on theirs. It's a clustered 24mm (3 motor) so that it can fly on D12s or E motors (for that realistic CATO possibility) and I've gone through and designed an e-bay that holds an Eggtimer classic, a camera, and a backup charge should motor deploy fail to do the job.
Having so much fun! So are the kids! 8 kids who've never flown rockets were introduced and they loved it.
