Involute Blower
thingiverse
With each passing birthday, blowing out candles becomes increasingly challenging; enter the hand-cranked blower as a helpful solution! Check out my training video at http://vimeo.com/73108405. The blades come in four different shapes: straight, involute, forward, and backward. One crank turn generates over 36 fan turns with default settings. On September 8th, 2013, I shared another video at http://vimeo.com/74023928. For M8 nuts, download the provided .stl files, and don't forget to explore other sizes by opening them in Customizer. My design is inspired by Vik Olliver's Forge Blower but isn't derived from it.
