Designed to be printed in two colors, this server room sign can be affixed to a door using command strips.
I've uploaded the ‘raw’ stl here. I printed this on a BambuLab X1CC and painted the ‘base’ layer white, with the raised areas in black to make it stand out.
The design is inspired by the multitude of ‘Droid Depot’ signs.
