Summary

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 coated to all sides.

I tried many different versions of this and finally feel it's shareable.

Instructions

This is indeed printable without support. I like to design most of my stuff that way if I can.

The filament hole did not print too nicely. I had to drill it out to make it useable.

The sharpie should fit snuggly in their holders. Depends how smooth your print is.

If pressed in fully, the markers make quite a pinch on the filament. I recommend adjusting them so that the you can pull the colorizer along the filament without too much friction, but still getting a good coat.

This thing ends up sitting atop your printer. It can hang on the filament and work fine, but the extruder ends up pulling it to the top.

If you decide to mess with the sketchup file, buyer beware. I did as best I could, netfab is your friend.

Respect from Greece :)

This would be cool with 4 different color sharpies

Wouldn't that just end up brown, though?

I don't know

Any chance you could post a picture of something translucent printed with 4 red sharpies?

Someone is wanting me to print a ruby for them and I'm wondering if this method would be better for getting that color.

standard red doesn't work too well. it comes out burnt orange.

This is brilliant. Thank you so very much - I can't wait to print it!!

Thanks for this it's a great print, and has been really helpful for funking up Christmas presents. Pens snapped in place easily though they had a tendency of coming loose again so I came up with a technique where the colorzier is inverted and each of the pen bodies is used as a table leg, drawing the filament up from below and pushing down on the colorizer with your other hand meant that pressure is applied evenly to all sides and an equal amount of colour is applied.
After quite a lot of use (I did mention that I had presents to make :p) I did notice that my nozzle started to clog but after removing and cleaning the tip and pushing some natural pla through it seemed to be working again n_n

love it. printing right now

Cant wait to see how it comes out and then what you colorize :)

I am so making this!

Is this ok for the extruder though? The sharpie chemicals going through the heat?

A great question. I have printed over 30 models with this now, and there is no issue. No clogging, no funny smells. Just fabulous, beautiful, colored prints. Couldn't be happier.

This is a great design, thanks for sharing it! I've made a derivative that fits on a Replicator 1 and this accessory is now a permanent fixture on our printer.

Thank you, I did spend quite a bit of time with different iterations. I can't wait to check out some of your colorized prints.

Not sure why nobody has made a copy of this thing yet. It saves me a bundle! I print in any color I have markers for, so I don't have to buy different color filaments. I just keep white, black and clear around. Handy!
After many many successful prints in solid and rainbow colors, this thing works.

Printed with blue on clear PLA this evening. It came it quite nice actually. Much more true to the color than red. I only had 2 blue sharpies instead of 4. Worked great. I'll add the photo.

when I used a black sharpie to mark distances on my filament when calibrating my extruder I would notice a small puff of smoke when the sharpie ink hit the hot end. Do you notice any significant smoking? I was extruding ABS so it was pretty hot.

I have only ran PLA at 195 and 200. No smoking at all. But I have noticed the color is lightly darker when at 200.

Have you tried running it through two of these?

No, but that's an interesting idea. That would put a lot of color on it for sure, but would require 8 markers of the same color. Worth a shot, but it may not be economically viable.

I second Weedz request. Would like to know whether I end up with just white filament colored with Sharpies, or if the color comes through in extrusion.

I added a made one that was done with white filament and red sharpies. Came out pinkish orange.

do you have some axamples of your coloured printed stuff?

Still printing things, but this one was printed in the red. http://www.thingiverse.com/thing:77401http://www.thingiverse.com/thi...
Notice you don't get the sharpie color, but a watered down version of it. I'm going to try some blue and other colors to see what I get.
