Wind Simulator Ducts for 120mm Fans - Sim Racing

thingiverse

Wind simulation parts that can be mounted to any 80/20 profile sim rig with 8mm bolts and controlled with SimHub, I recommend using at least 120mm x 25mm 2000 RPM fans, 120mm x 38mm 3000 RPM fans put out plenty of wind, but they can also start getting a bit loud so keep this in mind when choosing your fans, especially for those that race without headphones, having the fans attached directly to the duct will be louder than the flex-tube style wind sims that allow fans to be mounted elsewhere. I printed mine on a Bambu Lab X1C with a 0.4mm nozzle in PLA filament, lower res printers may have issues fitting on the decorative bezel parts as the models only have .004" clearance per side. All you need is an Arduino Uno and (optionally) a motor shield depending on if you use PWM fans or just regular 12v DC fans (I used the motor shield). There are plenty of Youtube tutorials available for both methods. Also, it's best if you orient the model with the outlet vent against the build plate to enable the decorative bezels to fit properly. I included a couple screenshots from my Bambu Slicer setup showing where I put the support. Here are Amazon links to the electronics I used: https://www.amazon.com/dp/B008GRTSV6?ref=ppx_yo2ov_dt_b_product_details&th=1 https://www.amazon.com/dp/B073SP76MC?psc=1&ref=ppx_yo2ov_dt_b_product_details https://www.amazon.com/dp/B07ZLSNLK3?psc=1&ref=ppx_yo2ov_dt_b_product_details https://www.amazon.com/gp/product/B00N1Y4QOI/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 You just need to cut off the barrel connector on the power supply and wire it directly into the Motor Shield. Here is a video by Boosted Media with the rest of the instructions, including how to set it up in SimHub: https://youtu.be/X2LS2IhGcdA Good Luck!
