Easy Jet Engine - By MC

I wanted to make a model of a jet engine that could be easy to print, with not too many pieces and that was able to turn, so here it is!
All you need is a couple of 22mm ball bearings with 7mm height and 8mm hole, those used in the fidget spinners.
It's not that long to print and if you build it well it will be fun!
Mine was not perfect so it has some frag, but it turns whitout many problems so i'm happy with it :)
It will turn just by blowing into the tubing connected to the combustion chamber section, if you have a compressor powerful enough to make it spin you should be able to use it (i only have a little airbrush compressor that is not capable of turning it, but blowing is fine :P)
Edit: I'm currently working on a turboprop compressed air engine, when the work will be finished it's going to be available
