Complete Water rocket for PET bottle and Euro Air-compressor nozzle

Thanks to AtomKemp for his work. I adapted his version in a way, that I converted it to the Euro air-compressor valve, added fins and a plateau to introduce a gasket.

Additionally I added a rocket tip and a tool to screw in/out the nozzle, without breaking the fins off (careful: the tool comes with 0 tolerance - just a subtraction. this will only work, if your printer is quite precise).

It works best with a 1l pet bottle. Only fill it about 1/3 with water. My compressor provides about 8bar
