The Spool Fan

Need a fan for your desk to keep cool? Doing some soldering and want a fume extractor? Build your own fan with some old filament spools! This was an interesting build for me, but I finally found a use for some of those Maker Supply electronics and I learned quite a bit along the way. This fan does push a decent amount of air for the motor and after 20+ designs for fan blades I found that fluid dynamics is pretty tough to get right. Follow the assembly instructions below and show off your homemade fan! Features Power on/off button Adjustable fan speed Adjustable fan position. The fan can tilt up/down and side to side. Easy to assemble and fun to build! The fan will push air. I am currently working on a pull design for the fan blades. Notes This design has only been tested with Bambu spools.
