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:
