K2 Plus Exhaust, Dual, Single 4" & 2.5" Options

Here are a few options for exhaust/ducting for your K2 Plus.

All-in-one This is a single large piece which takes the output from both exhausts and takes it down to a single point. Attach your hose/duct and then attach the hose to a venting system or out a window. You must use PETG/ASA/ABS and very strong mounting tape, otherwise it will likely come off at some point.

Split These are individual pieces which take air from each output. You can then connect two hoses and vent them, or use a Y splitter like the one here https://www.printables.com/model/634619-4in-4-inch-duct-splitter or here https://www.printables.com/model/1099216-25in-25-inch-duct-splitter to connect the two hoses into one. There is also a 2.5" magnetic version that uses 6x 20mm x 3mm magnets. I glued them so they would have direct contact with the printer & they protrude just a little so that mounting tape can also be added (for extra hold and a better seal).

I have not printed any of the 4" versions and don't have a 4" hose so I don't know if they will even fit.
