Desk fan

Hello,
I made this blueprint for the 5-12V brushless fan I bought online. I don't know what the brand is, its dimensions are approximately 142x25mm. I use it with a booster circuit from 3.7V to 6-9V (2 modes). This is a simple design that suits my desk, you can edit it according to your requirements, I will attach the .obj file. To connect the details, you will need some M3 screws and nuts. Power source is two 18650 batteries, large capacity will extend the usage time.

If you need any assistance, please contact me directly via Facebook or leave a comment.
