Antminer Long Duct to pump air outside

This is an Antminer series duct that should fit the S7,8,9 as well as the L3 and D3
This has about 130mm ducting built in so you can place them near a window and blow the air right out, this was a remix of https://www.thingiverse.com/thing:1630533 however his step down drastically increased my temperatures noise and fan speed so this remake has no step down and is shooting straight out with minimal air resistance
