Air Powered Spinning Top

This is a simple air powered top that you can spin by blowing on it. There are two versions of the file. One of the STL files has a separate spinning knob that needs to be glued or friction welded onto the top. The second file is an all in one design. I injection mold this air powered top design so most of my tops are the all in one design. Here is a video of the air powered top in action (also includes a scaled up print.) https://youtu.be/ConPkDFKoYw Additional information about my injection molding setup can be found here: http://www.scorchworks.com/Injection_molding/injection_molding.html
