I 3D printed a nosecone, fin section, and motor retainers for a BT-55 tube (this one: https://www.thingiverse.com/thing:685617), gathered up a couple of motors, scrounged a chute from my plastic chute collection and shock cord, and delivered it to a (younger) coworker so he could launch a rocket with his young kids. Excepting the 3D printed stuff it's all stuff that I've accumulated for making rockets for my grandkids. I need to find my kevlar shock cord stash. He'll need a launch rod and launch control box but neither of those are too hard to come by. I almost built it for him but that would take away some of the experience imho
