Desk Fan

This is a desk fan designed to use the following off-the-shelf components:

• Arctic P12 Pro fan

• 4x M3x12mm button head cap screws

• 2x M4x25mm socket head cap screws

• 2x M4 nyloc nuts

• 1x 2K potentiometer - https://www.amazon.com/dp/B082FC2BY4

• 1x 1100 Ohm resistor

• 1x DC buck converter - https://www.amazon.com/Zixtec-LM2596-Converter-Module-1-25V-30V/dp/B07VVXF7YX

• 1x 5.5x2.1mm DC barrel jack - https://www.amazon.com/dp/B01N8VV78D

• 1x Pushbutton switch - https://www.amazon.com/Gebildet-Latcting-Lockable-Trumpet-Doorbell/dp/B07YDCJFZJ

• 1x 120mm fan grill

• 4x rubber feet, up to 21mm in diameter

• 1x DC power supply, can be anything from 12-30V

Everything is designed to be printed with 0.2mm layer height. I used Overture PLA Plus.  I included two versions of the air amplifier, in case you don't want a Noctua logo on your Arctic fan.

You will need to desolder the onboard potentiometer from the DC converter so you can solder the leads from the new one in place.  The 1100 ohm resistor needs to be be soldered in-line with one of the potentiometer leads.

Before installing the lock nuts, I recommend running a screw through them to cut some threads in the nylon lock ring.  That will make it easier to thread the knobs in during final assembly.
