Node 202 - Customizable cpu fan duct for Noctua NH-L9i cooler

thingiverse

I remade this with OpenSCAD to allow customization by modifying only a couple variables. It will generate an STL with dust filter side laying down for easier printing. The provided STL is designed to fit my setup: Noctua NH-L9i cooler Intel i5-7500 (any socket1151 CPU, really) MSI B250I GAMING PRO AC Better airflow can reduce your CPU temperatures by 10-15°C. Right now it's printed in PLA and the CPU reaches 60°C, but I don't see any warping. If your case reaches higher temps, suggest printing in PETG or ABS. *Small update Aug 2020: No warping at all, PLA is good enough for my temperatures.* ***UPDATE (02/02/2020):*** According to a couple DMs I got, this can fit AM4 boards with Noctua L9a-AM4 by increasing duct_height base value from 38 to 40.5. Also according to another user, this will fit a Cryorig C7 cooler with the same motherboard as original maker (ASRock B450 Fatality Gaming ITX/ac), but he didn't tell me his values. Last thing I have updated scad comments with a better description of how and where you should measure both offset values, as it wasn't really straightforward initially. If that is not the case, original maker made a better explanation with pictures on his Reddit post.
