What you'll receive after downloading the project: 3MF file: project Anycubic Next Slicer (based on Orca Slicer). This file contains a ready-made project for printing on a Kobra S1 printer equipped with one Ace Pro.

I assume that the project can be printed on other color FDM printers, not only the Anycubic Kobra S1, but I only have this printer and I have no way to verify it.
