The AC vents on my '95 defender were broken and had missing pieces, so I created some spare parts to repair them.
It is quite fiddly to dismantle them, and same goes for putting them together.
make sure to drill out all the holes to 2,5 mm where the louvres would fit.
the louvre needs supports, all other parts print fine without.
I used PETG 0,2mm
