A Simple Desk Fan

This is a simple desk cooling fan. This might not work with every fan, I used this one: https://www.banggood.com/custlink/mDmDPtRs8n. Furthermore, I used a boost converter and a USB cable to power it: https://www.banggood.com/custlink/3v3GtBlcS2. Instead of a wingnut, you can also use this: https://www.thingiverse.com/thing:163883. If you are connecting it to a PC/Laptop and it is giving an overcurrent warning it might help to snip off the lights. No support is needed to print this.

E1: Added a fan duct, so the air is directed better.

E2: Added spacing for a 4mm fan grill and spacing for the fan to lay flat.
