Ventilation Grille 100mm

I would recommend printing with either PETG or HT-PLA.I've had success with PLA as well but might not withstand weather as good. A layer of clear coat might do the trick though. I used “Support/raft interface: PETG” when printing with PLA for easier support removal. There are similar design that doesn't require support, but I like this better partly for more rain resistance but also the esthetics of it. It just looks better IMO.
