thingiverse

This portable fan is designed to move huge amounts of air, and it's a very powerful Arctic 140mm fan for PC desktop use. It's incredibly silent too! The fan can be used with a 3S battery that has an XT60 connector, or any other 12v supply unit with an XT60 connector - the fan consumes only 0.110 A. The battery inside is a generic 18650 Li-ion cell charged using a TC4056 chip micro-USB or USB-C. To power the fan, you'll need to add a step-up converter to convert the 3.7 V of the battery into the 12V needed by the fan.
