I needed a replacement for my Toshiba portable AC vent. The round one slips into the spot on the machine and can connect a 6in vent hose to the other side.
The window section is 3 parts screwed together with a piece of screen to keep out the bugs. The middle piece can be adjusted on z axis for thickness or can use without depending on your window setup and need wood/cardboard/etc to cover the window gap but works great.
I printed in PLA but probably want something higher temp.
