Adjustable Speed Desk Fan

The goal of this project was to create a simple, aesthetically pleasing desk fan that accommodates a 140mm case fan, moving just enough air to provide a gentle breeze at your desk. This is my first 3D printing project involving electronic components. I have made one for both my desk at home and work, and I love the results. Electronic Components: 4-Pin 140mm PWM Case FanYou can use any 14mm PWM fan you would like. I strongly suggest using the Arctic P14 Pro, as it provides a higher RPM than typically found in case fans, produces a nice/noticeable breeze, and is reasonably priced for this type of application.Arctic P14 Pro: https://www.amazon.com/dp/B0DPX5PD99USB-C 5V-20V Power Delivery ModuleThis case is designed to house a specific USB-C module.Here are a few places it can be purchased (as of 08/15/2025):https://www.amazon.com/dp/B0F2H5V51Qhttps://www.aliexpress.us/item/3256809210646472.htmlhttps://www.aliexpress.us/item/325
