Ender Filament Coloring Guide

thingiverse

I've been dyeing filament for quite some time now, opting to save on costs by not having to purchase special colors for one-off projects. Generally, I take a sharpie insert, snip off a part of it, and then wind a certain amount through the felt. To create this little guide, I mounted it onto the back of my printer's Z-Axis. You need to cut off about 10mm of the insert and seal it up, then run the filament through it. As you do so, it will start coloring. Having it sealed inside helps slow down drying significantly as well. Simply remove it and use it like normal filament if you don't want it colored. I utilized the existing Z axis bolt and a single small M3 screw to secure it in place.
