The pattern prints face down, so make sure your build plate is clean. You can rotate the model if you want.

Version V2 (pictured): In the ‘shaded’ part with both colors, I doubled the amount of red filament put down.

Version V3: I've aligned the pattern to the shape of the swatch better. It was bothering my OCD.

Filament used:

Inland True Red PLA+

Bambu Basic Black PLA
