About this 3D model

https://www.youtube.com/watch?v=PzvsCiyBClc Hello! As a part of the one day Project challenge I made a device that can blow bubbles with only a handle to turn and a balloon! I had a lot of fun working on this project and I had more trouble that I'd like to admit. I'm a 16 years old student from Israel playing for the local robotics FRC team as the head CAD department. Time to design and tinker: 4 hours Time to Print: 11 Hours (a few tries) Clean-up and video making: 2 hours Have a nice day!
