NFC tag case to have a sample of the color of the filament.

It's parametrized to fit multiple tags using the scad file. Important parameters are tag_diameter and tag_thickness. Default parameters are for 25 mm diameter and 1 mm thick tags.

Used with Ace RFID to program the tag to the color of the filament for Anycubic printers. More info about Ace RFID on their GitHub page. I have no affiliation with them, please contact them for questions about software.

There is probably other software for other printer brands.
