3D Print Colorizer is a combination of 3D printed parts and a Cura plugin which allows anyone with an Ender 3 or BLTouch-compatible printer (no CoreXY for now) to produce multi colored models. Have a look at some results:

• 2021-08-06 Fixed issue with some T-Commands still being in the G-Code as reported by Teaching Tech.
• 2021-08-05 Added big compatibility update. Added parts to mount to nearly any BLTouch-compatible Printer (no CoreXY for now).

3D Print Colorizer uses Sharpie or Sharpie-like permanent markers to directly paint on the layers of a 3D print. After a layer is finished printing normally a pen holder, which is mounted to the print head, is used to fetch pens from a special pen rack mounted to the top part of the printer. Normal printing and painting is used alternately to produce a final colored model.

To coordinate the process a special Cura plugin is used to add the painting G-Code. After installing the plugin you need to enter some calibration values and afterwards models sliced for an Multi Extrusion printer can be printed on an Ender 3 with full color support.
