描述

the ball fan is an easy to assemble desk fan. a simple 4.5v motor, 24mm in diameter, will fit snugly into the back cage, and can be bought from any electronics store.
if you wish to create a custom base, the entire cage is 92mm in diameter.

the design itself is inspired by u-like’s ‘usb desktop fan’, and 11+’s usb-powered ‘o-fan’.
