This is a 3" hose adapter for the QIDI XMAX 3 and a corresponding low profile window exhaust. The window exhaust (and spacer) were designed specifically for my window, so likely you'll need to do some work on it if you plan to use it instead of a dryer window kit.
The printer side connects via the normally screw holes. You may need longer screws but I was able to attach it with the existing.
Printer vent needs no support, the window vent, you'll want to support the lip area and block supports on the rest of the model. I used ABS for the material.
The author marked this model as their own original creation.
