About this model

This print allows you to color your filament from 4 sides using sharpies (a common marker in the US). I am experimenting with different colors and filaments but the rule seems to be that the colors mix with the filament. So white filament with red marker produces a pinkish orange color, while clear filament makes a translucent pinkish orange color. Let's see what you come up with. [Update: the colors that come out of the extruder vary depending on a few things: what color filament you are using, what color and how many sharpies you use, and the heat that you extrude. Hotter temps seem to brown the color.] There are 4 holes sized to the tip of a sharpie marker. When you push the markers in, the tips should all meet at the same place. Slip your filament through the hole and watch as color is…
