Rocket launcher

You can print my design for a rocket launcher. You will need a pressure tank that connects to the launcher. I have also designed a rocket with different holes for various dimensions. Additionally, there is a test rocket that allows you to determine the best fit for your needs. If you want you can build your own rocket with paper or also 3d printed. I have personally experienced that a paper rocket works best. Things needed for the launcher:2 O-rings (outside 14 mm and inside 10,5 mm)Camera stand M10 air connector or a flexibel tube How to build:Assembling the launcher is very easy. Slide the O-rings onto the launcher part. To let the air pressure into the launcher, use either an air connector or a flexible tube. For the flexible tube option, you can use a tube with a minimum diameter of 4 mm and a maximum diameter of 8 mm, which can be glued in place.
