These are some super simple signs I designed for a friend. They're all sized at 25x15cm and are only 2mm high. They're meant to be adhered to a door with double-sided adhesive strips or tape, so no mounting holes for screws are included, though I could add them if someone required them. I printed them all in PLA, though I would guess something like PETG would hold up better in direct sunlight if that's where it was to be mounted. A clear coat would also likely help with this.
