Fan-freaking-tastic

I recently found myself stuck on a sweltering streetcar with temperatures soaring above 95F, and knew I had to think fast to cool down - which is exactly what happened when I hatched the plan to melt some plastic into action. https://www.youtube.com/watch?v=181IDoGvFy4 https://www.youtube.com/watch?v=zS9lyGbMXlM The whole design is parametric, so feel free to download and print out some examples or generate your own fans using the included OpenSCAD file. Don't let OpenSCAD intimidate you - it's surprisingly easy to grasp in under 5 minutes! Add some texture to your fan by drilling holes (use a third-party app for this - I used Tinkercad to create the one shown). For an even more impressive look, change up the filament color after 0.6mm. This will give you blades of one color and arms of another. Make sure you've got a Bottom, Mid, and Top file for each fan design. The suffixes tell you all about the dimensions: r = mm length of fan arm, b = % of fan arm that will have blade, a = angle (arc) of each fan blade, c = count of blades, s = position of slot-notch that holds blades to each other as percent of fan arm radius.
