Air Vortex Cannon

This is a fully 3D printed air vortex cannon, capable of shooting the vortexes of rotating air up to 10-15 meters. I designed it for my kids and it was really cool to play with it so I decided to share. Absolutely safe to use, it only gives a fun surprise effect when hitting a person with the vortex. This design fits the 256*256 print table (P1P/X1 etc), possibly can be re-scaled to other printers. Concept is similar to commercially available AirZooka toy, but was designed from scratch and optimized to be fully 3D printable and lightweight.I printed it from PETG and it's strong enough to withstand some drops during kid's play.Let me now in comments should I make a walls thicker for more robustness etc. To assemble it, you need only this additional items:Rubber bands - 4pcsShopping bag - 1pcsAssembly video:
