DIY ac unit fan duct

This model works on the DIY ac unit (https://makerworld.com/en/models/1029164#profileId-1011587). You just glue the 2 pieces together and glue it to the ac unit! I used a normal washing machine hose with a diameter of 30 mm. I have it set up so that i can suck the hot air away from the 3d-printer and there is place for a filter in the connection from the hose to the duct. For me, the hose was a bit smaller at the duct size, so i used another 25 to 30 mm adapter, and i then screwed that one to the 30 to 40 mm adapter that was already on there
