Description
It's summer and the sun is very hot. Buy a fan is boring.
So why don't print a selfmade fan with 5 speed steps? - from silent to cool down! ;-)
What can you do next? Take this fan to a place where is a lot of wind or use wind enery from a exhaust of a machine and use it the other way round to produce energy!
Have Fun!
