Items you will need;
Cardboard tube 110mm X 24mm ID, 27mm OD (or cork sheet to line motor tube)
Parachute cord (approx 150cm)
Parachute (45cm to 60cm)
Dog Barf (Fire resistant wading)
Two-part epoxy (5 minutes)
24mm Rocket Motor (Aerotech disposable F's is my choice)
Launch Rail (or rod) and launcher
Optional (For nosecone)
Eyebolt 1.5cm X 2cm
Quick Link for eyebolt
NOTE! Some knowledge of model rocket building is required.
If using Estes-style rocket motors, the retention screw will not hold the motor in place and will have to be pressure fit using masking tape.
No supports are required for any printed parts.
All parts with the exception of the Fin Can are to be printed at 100% infill, .2 layer height. The Fin Can should be printed at 20% infill with 4 layers and a .2 layer height. All parts are oriented for the best print.
If printing the fuselage in two parts, (the Full Fuselage is 305mm!) use the Fuselage sleeve to join the two halves with epoxy, being careful not to leave ridges that your parachute could get caught on.
The nosecone collar may need slight sanding for a nice smooth fit to ensure optimal parachute deployment. Also, the nosecone bulkhead is printed separately from the nosecone to allow you to decide how much additional room you may want for parachute gear.
The fin-can has a recess for anchoring the lower end of your parachute chord. Fill that recess with epoxy and one end of your deployment rope in there before you epoxy the lower fuselage over the fin can to have it anchored solidly in place.
I've included either 1010 rail guides or launch lugs. Be sure these are well aligned when gluing to the fuselage.
Use epoxy with all parts except the retainer screw and the nosecone collar.
I have added the Open Rocket file as a .txt that will have to be changed to a .rkt to open with Open Rocket if you would like to run simulations with the motors of your choice.
I embossed mine with the Ukrainian coat of arms because I had the right colors on hand :)
