It's a head-spinning 10-Fer! Ten fans for ten bucks! These cute little 2" square 50mm muffin fans by Runda operate from 6-18VDC, and they’re rated at 18 Volts. They’re pretty gusty at 12VDC and run strong off a single 9-Volt battery. Each fan is 10.5mm and has (4) mounting holes in the corners. These are take-outs from unused equipment, and super clean. Great for group projects. Think: Scouts, classrooms.

Of course you’re not, but you might like squirrel-cage fans like we do. If so, this take-out, cream-colored ABS plastic squirrel-cage blade is for you. Originally from portable AC units, they measure 6-3/4" dia x 3-3/8" across with a flattened 5/16" ID bore and a 3/4" shaft that extends 7/8” into the cage. Could be re-rigged for a gerbil wheel. Made in USA.
