Wind simulator / generator for simulator games (140mm fan)

thingiverse

This is my debut major design project, where every single component was meticulously crafted by myself from scratch. Each part was designed using Tinkercad, with numerous revisions along the way before finalizing the design. In total, I spent around 15 hours crafting these components. This model was specifically built to utilize the wind feature in Simfeedback, but it can be adapted for use with various other controllers such as simhub/simwind and others. The fans used are Noctua 3000rpm 140mm fans, which are controlled by a PWM signal from an Arduino Uno. As a result, there's no need for any additional equipment like monster moto or anything else beyond the uno for control purposes. A reliable 12V power supply is also required to power the fans. I decided to design my own parts for the bracket as well as the flow straightener because I couldn't find suitable alternatives that met my requirements. The options available were either too flimsy for a moving SFX-100 platform, too large and heavy, or ineffective in terms of airflow straightening. After printing multiple versions, I finally designed my own parts. In my design, I utilize a honeycomb mesh approximately twice the length to its diameter for each "tunnel", which should be sufficient for straightening the airflow. This is supported by my own testing and data collection. The following components are required for printing: * Airflow straightener * Back frame (please choose LEFT, MID or RIGHT version based on your mounting location) * 4040 M8 Gopro mount (You can use any other gopro mount instead if you prefer, but this one has screw holes for M8 screws which I use for most mounting on my 8040 rig) Optional components include: * Spacers I printed all the parts without any supports or adhesion using my Ender 5 printer. My hotend is a titan volcano and I used Geeetech black PLA filament. You may want to add some between the lower screw holes on the top of the frame, but for me it printed fine with only minor cleaning required with an exacto knife. For other parts, please use at least 3 walls and at least 25% infill, but I recommend >50% infill for the mounting bracket. The spacers are provided to be applied between the screw holes in the noctua fan, as tightening the screws too tightly would otherwise cause the frame to bend. While not absolutely necessary, I highly recommend using them, especially with a motion platform. It would be fantastic to see this project come to life and posted online. I'm eager to hear your thoughts and comments. I'm thrilled about my first major design and hope you find it useful too. In the future, I'm looking forward to perhaps receiving my first tip as a designer - that will indeed be a glorious day.
