Abstract

Update
Wow, thank you all so much for your support! I'm really thrilled that this desktop fan has attracted so much attention—especially considering this is my first attempt at 3D CAD design in my life. Unfortunately, for various reasons, I wasn't able to respond to everyone's comments and requests as promptly as I had hoped. To address this, I've uploaded the latest STEP file for the desktop fan: the fan head is already complete, but the 120mm fan base still needs further refinement, including various functional tests and installation holes for the switch and power cable. However,

In addition, I have also shared the design publicly through Fusion 360, and the relevant link is as follows:

At that time, I urgently needed a new desktop fan at my company. I had just started learning Fusion 360, and I happened to have a spare 70mm computer cooling fan and a 12V transformer on hand. So I had a brilliant idea: Why not design a bladeless fan myself? This fan is not only easy to print and assemble, but even the wiring is almost the most basic operation.

Assembly steps:

1. Fix the computer fan inside the base and firmly embed its bracket into the base.
2. Pass the electric wire through the threading hole on the bracket.
3. I welded the wires of the fan and the transformer to a switch
4. Gently insert the inner shell of the fan into the outer shell of the fan. There's no need for additional adhesion. Just align the tabs, and you can easily snap it into place and secure it firmly.
5. Finally, install the entire fan inner/outer shell into the base—it's so simple!

• Note:

  Fan housing:
  Support structures need to be set up everywhere to ensure the quality of the molding.

  Fan inner shell:
  Although I used support printing throughout the process, I personally believe that even without adding support, the finished product can still maintain good accuracy and strength.

  Fan base:
  Using the inverted printing method, only the support and the build platform come into contact with each other.
