Wherever this sign is placed, it becomes law. NO SWIMMING!
This model is split up by color with two different tolerances. The "Easy.stl" versions have a 0.25mm clearance between parts, while the others have a 0.13mm clearance.
I glued the parts together using E6000 adhesive and held in place with binder clips overnight.
You can flip the black graphic 180 degrees in the X or Y orientation (face down on build plate) if your printer makes excellent first layers. I like the gloss it gives on glass build plates.
