I made this design a while back but haven't posted it until now in honor of Matthew Perry's passing.

This design is pretty massive the print in the thumbnail was scaled down to 50%.

The base of the design (the white) unscaled is 5mm.

The white and black can be printed but the red, yellow, and blue dots have to be painted.

You could also do a variant print with the base being black and the letters being white.

Please post a make to show me what you do!
