The file 'Dometic Caravan Exhaust Cover 3D Printer Model' is (stl) file type, size is 56.8KB.
The cover for the exhaust when using the fridge on gas(Gasol)Might fit other brands as well, I don't know!
My test print was PLA but I will print one in ABS to use.You might need to scale up the model, see comments.
