Hello,
This is the file you need to print Tesla K20/K20X/K20Xm 92mm Fan Shroud. Originally Tesla K20's come with passive cooler. This model adds an active cooler mount (92mm) which lowers temperature significantly. I've used old AMD Wraith Stealth (92mm diameter) to active cool the accelerator. You can use any other 92mm diameter fan, just make sure you're wenting heat out of the case, not into it.
Designed to be printed with PETG or ABS
Also you can order this printed and assembled via contact me.
