USB C Powered Fan - No Soldering

Do you want to build your own powerful desk fan but have absolutely no clue about electronics? No problem! 

Designed for makers who want don’t have a engineering degree. If you can handle a screwdriver and know how to plug in a USB-C cable, you are ready to build the best upcycled fan on the market. and by the market, I mean the five minutes of research I did before starting this project. 

Most DIY fans are "gentle breezes" because they run on weak 5V power. I think your empty spools deserve better. By using a PD Trigger and a simple "Plug-and-Play" PWM controller, it's possible to run a real 12V motor directly from your phone charger. 

The best part: No Soldering, No Programming, No Guessworking. Just follow the simple wiring layout, and you're good to go! Everything connects with simple screw terminals, and the parts will cost you less than a 10er on Aliexpress or other platforms. Also, it is maybe a nice project to build with your children to understand the basics of electronics. 

 It’s easy, it’s fast, and it blows the competition away! 

Bill of Materials 
- Motor: R-385 DC Motor (6V-12V) 
- Controller: PWM DC Motor Speed Controller  
- Trigger: USB-C PD Decoy/Trigger Board 
- Connectors: 2.8mm Spade connectors 
- Wires: Some 22 AWG Wire
- Super Glue

Note: I wanted to make this modell to run on a USB-C Power Charger from your phone. It turned out, that in MY case the Charger and the PD Trigger didn't speak the same language. I hadn't had a other charger to test with so i ordered a 12V DC hole cable and female connector also with screws to connect. But it should work with better phone chargers than mine. In case you want to do it with a DC charger also the Female part fits on the same spot as the USB-C cutout. 

Installation:

Note: All parts are very much press Fit so it doesn't rumble when the fan runs. I tested it muliple times an had a lot of missprints, but all parts work now on my printer. 

First you see the way it gets wired. When you test it, and the motor runs in the wrong direction just switch the wireing.

The PD Trigger on the left has 3 switches. Set them to 12V. Please do not set on 15V or 20V. The Motor is just made for 12V maximum. 

Press in the Back Cover Connector and lay in the legs.

Press in the Motor in its holder and in the spool. Please print the Motor Holder in PETG because of possible warmth. 

Put the electronics in their designated places and connect the backparts to the spool. 

Glue in the red Connectors to the spool. Notice my highly proffessional markings to find the right place for your connectors. Also glue them fromt "behind" so they dont collade with the fan later. 

Now i run out of pictures so this is a screenshot from a video. Connect the Red Front Cover and the Flights. Lay in the other part of the spool and finish with they gray "Designpropeller" (after that it gets steady, i promise).  

Snap on the grill gates and you are ready to go. 

I hope you have fun printing it. It is my first ever uploaded file to a Site so please forgive me if anything doesn't work and let me know.
