Print your rocket. Requires some materials you can get on a hobby store.

Assembly

Add extra “flame resistant material" the first time, otherwise the body of the rocket might explode in mid-air
The tip should interface the rocket body with little friction
It is safer to “crumple” the elastic, keblar, parachute inside than to wrap them tightly together (it might not deploy)

Have fun!

Cut a piece of the 1-2mm elastic and 1.3-1.5mm keblar thread	Attach the keblar thread to the ring, pass it thru inside the side of the rocket body	Pull it from the front
Tie the elastic to the keblar	Attach the elastic to the tip	Prepare the parachute. I am using a plastic bag, distance between the points passing thru the center is 40 cm.
I added some sticker rings (check the RAW files for the SVG to cut your own). Cut 3 thin threads as shown	Attach the threads so the parachute takes form	Tie it to the tip. Pass all the 3 thread loops thru 2 holes, and then pass the whole plastic bag thru those loops, this way makes it easy to replace damaged parachutes
You need some flame resistant material to fill the inside	The second stage will push the filler with the tip and parachute. Now you can place the parachute inside and the tip at the end	You need rocket engines from your hobby store. Try A6-4 as a starting point. B4-4 and C5-7 are also ok.
The engine goes as shown. Put the wings	Use the lock to keep everything in place	Rocket is ready now. The wings have a hole for a metalic guide (or launch pad) you need to use. For ignition I am using this remote
