Exhaust fan duct for connecting a 80 mm hose to the exhaust ports of the Creality K2 Pro. They connect to the back of the printer using magnets so they should work on other printers with a metal backplate as well.

I created two versions, one which uses 10x3 mm magnets and one which uses 6x2 magnets (used by gridfinity).

A simple guide is included which can be screwed on to the back of the K2 Pro for easy alignment of the fan duct to the correct position on the filtered exhaust in the middle. For the top exhaust a simple hole which aligns with the screw on top helps with alignment for the top exhaust.

Also included is a simple ring clamp for connecting the hose securely to the duct. Use a heat insert and screw or just a screw and nut for fastening.
