Wind Maker / Fan Amplifier

thingiverse

If you like this or it benefits you, consider leaving a tip. Sleeping in the fall after it's cooled off outside can be tough for me at times. I get used to the sound of a fan all night in the summer and then when that is taken away in the fall I don't sleep well until I adjust. This amplifies the internal fan noise and its natural wind sounds, allowing you to more comfortably adjust or just fill the silence with some sound. Based on the position you set the holes in the housing, the volume and pitch change, letting you customize the experience to whatever suits your needs. For this project, you'll need a 120mm variable speed (optional) computer fan, a 12 volt power source for it, five M3x10 screws, and a 15x21mm on off switch (also optional). Check out the pictures for each stage of the design. These are the switches this was designed for: https://www.amazon.com/gp/product/B01N2U8PK0/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 (If using WM Inside Top V2, you may need a screw shorter than 10mm. Test the length before assembly.) Here's how to build it: 1.Remove the fan frame from the fan. 2.Glue or attach the fan to WM Inside Top (or WM Inside top V2 - Note:V2 will likely require you to extend the variable fan cable, but this will increase the amount of customization possible). 3.Sand the WM Inside Bottom so that WM Outside Sides can slide smoothly over it. 4.Add nuts to WM Inside Bottom and then glue WM Inside Top to the WM Inside Bottom. 5.Glue power and speed control wires out of the way of the fan. 6.Run Wires through WM Bottom and screw WM Bottom to WM Inside Bottom. 7.Apply a bit of grease to WM Inside Bottom (optional for increased ease of movement) and put WM Outside Sides over the top. Finally, add WM Outside Top and screw it on with the single middle screw.
