You will need co2 cartridges, these 7,5g worked great for me: https://www.slehame.cz/sifonove-bombicky-kayser-7-5-g-co2-25-ks-na-jedno-pouziti/

Also get a 1,25m PVC pipe with 28mm inner diameter (32mm external diameter)

Then print these parts, mount a 4mm screw into bottom part(40mm height worked great for me).

Insert bottom part into pvc pipe, insert cartridge into rocket print and you are ready to launch!

It can be really dangerous be sure that you are in safe distance from the launcher, attempt to build at your own risk!

You will get best results if you will lauch rockets from hard firm surface(concrete).

My best launch:

Have fun!
