The Customizer supports the following Standard Configurations: 36,38,40,52,60,80,92,120,127,140,150. Select your configuration or build a custom one. There are a few parameters that you should adjust to your liking such as the number of rings and vanes and their associated widths. There will be more standard configurations added so that you don't need to measure your fan.
This isn't the first customizable grille however I believe I have worked to decrease the amount of plastic needed, time to print, and increased air flow.
If you have any questions, or find a bug sned me a message.
Thanks for checking out the Customizable Fan Grille and Happy Printing!
