Easy print A3 mini model rocket

thingiverse

A mini rocket that uses an A3 engine. Also, a complimentary launch pad that uses three guide wires so it can't launch any direction but where you point it. :) I designed this to be as DIY-ish/accessible as possible. The launch pad is comprised of three low-profile aligning plates that have holes that will fit the gauge of a hanger wire. Use wire cutters to remove the longest length of wire from the hanger and bend about one inch of one end of each wire 90 degrees perpendicular to the wire (see attached photo). Feed the wire through the three holes of each aligning plate and secure to a suitable launch pad like a block of wood or less combustible soft-ish material. I made my ‘parachute’ by securing a piece of string to the base and tip of the rocket. The tip unscrews so it can be accessed more easily. The ribbon should tuck easily into the top half of the rocket. Slip both halves together with ribbon inside. Then, find an A3 rocket engine and friction slide it into the business end of the rocket. Align the wires with the recessed ridges on the side of the rock and pass through both sets of wings. Slide the rocket down to the launch pad. Finally, launch it safely and enjoy. Here it is flying to the sky: https://youtu.be/yAPwLe6MEjM If you found this useful, it would bring me great joy to see your work - so be sure to share. :) Or, better yet, please feel free to dump a bitcoin or two here: 1Py3TUeR8noBN2giHyFV1GfB6x3Kh2WEVv ... include a note to the effect of "Hi Julius3E8, thanks for the [insert name of thing]... my life has improved five-fold on account of it and please accept this paltry amount in gratitude".
