Looking to add multiple colors to your prints but you can only afford a less expensive desktop 3D printing system with a single extruder where your only option is to stop the job and manually swap out the filament? Check out this fun idea that was posted on Hackaday: a simple 3D printed mount that attaches to your printer, and holds up to three colored Sharpie permanent markers against the filament right as it’s going into the top of the extruder.
Maker Devin Montes, who runs the YouTube channel Make Anything, enjoys creating, in his own words, “both functional models and delightful objects that spark inspiration.” I’d say this 3D printed Sharpie mount, which Montes has published on 3D printable design repository MyMiniFactory, would fall into both of those categories.
“I made this tool that holds 3 sharpies that color your filament before printing,” he wrote. “The results were surprisingly beautiful!”
In order to make desktop 3D printers less expensive so they’re more accessible to all users, nearly all of them use single extruder setups, which means there aren’t a lot of options for multimaterial printing. Hackaday writer Tom Nardi does admit that from “a practical standpoint, …
