Space Airmill

pinshape

Inspired by Jamie Hyneman and Adam Savage's curve ball toy as seen in the video at http://chrishadfield.ca/videos, we built an airmill for space! Using a 624z bearing (4mmx13mmx5mm), we crafted an easy-to-assemble mechanism requiring no glue! The airmill consists of the main body, the caps, and the bolts. The caps snap into the main body, holding the bearing in place while allowing space for the bolts to be inserted. The bolts, which serve as handles, fit snugly into the bearing, enabling the mechanism to spin freely from friction. When assembled, all you need to do is push the bolts and blow towards the airmill blades! With the help of the bearing, the mechanism operates efficiently. Once released, the spinning space airmill will follow a non-linear route, much like a baseball throw. In zero-gravity conditions, you can use it as a darts game, navigating obstacles to hit your target. We 3D printed the airmill with a 0.35mm nozzle (0.35 - 0.4mm recommended nozzle size) at 0.2mm layer height, 2 outline shells, and 30% infill. You can print it without supports at the desired infill.
