I needed a sign for my workshop entrance to warn people getting into it, that there is a laser in use.

Currently this sign is made and used in germany according to the usable symbols and the classification from DIN EN 60825-1:2022-07 (latest version).

If you own a diode-laser, CO2-Laser, fiber-laser you should have this sign to warn people, since its needed for business, but also for private use to prevent any harm to people.

The model is designed as multipart, so it is very easy to color it up in your slicer (see picture).

I've printed my sign in PETG - looks awesome.
