Needed a custom fan shroud, so I printed one.

Wow! That seems like a reasonable amount. It looks good. Does it actually help?

Yes. Stock put the fan inside the shroud. Tried to modify the stock one and that went no where. On this one I think I could pull it back another 1/4" to be centered. Figured if it broke or I needed to reprint it for any reason I'd adjust the depth. Its about 2/5 out and 3/5 in the shroud.
