First, I’ve got to admit that i don’t have a 3D printer, but I have a friend who prints stuff for me.

For this project, we need ABS as material. My friend has several years of commercial experience and research in this area, so it take this as granted.

While he has a good match for “Light Bluish Gray” and “Dark Bluish Gray”, his “Blue” is off in comparison to blue LEGO bricks.

Has anyone found a close match that would be worth trying?
