Orbis Rocket Parts
thingiverse
Model rocket parts from Estes, re-scaled to metric so they just work in most slicer software. These are parts from the Estes 'bulk' pack: https://www.estesrockets.com/001706-orbistm-3d-bulk-pack-12-pack These are designed to work with a BT-20 body tube. I highly recommend buying paper body tubes rather than 3D printing them, since a printed body tube adds a lot of weight. For a complete rocket build you will need: * Nose cone * Nose cone 'pin' (cap for nose cone) * Fin unit of your choice * Launch lug ring * Standard engine mount ring * 9" BT-20 tube (standard tube is 18", so you can make 2 rockets from one tube) * Engine retaining hook (I make my own from thick paper clips) * Recovery system of your choice. For this size rocket, I like to use a streamer, 1" wide by 2 foot long. Mylar gift wrap works great, light and helps make to easy to find the rocket. Try an A8-3 for first flight, B6-4 for second flight.
