Doublesided and easy to print door sign with a green and a red side (tick and cross).

The white cross and the tick are on the same level as the rest of the surface, i.e. no support needed.

However it is crucial to print it multi-colored, otherwise the sign will be blank.

I printed it in PETG for a slightly better durability, but any other material (PLA, ABS, ASA) should work as well.
