Printer (my printer): Anycubic Kobra S1 with one Ace Pro (4 colors)
Colors1: (1) gray; (2) black/dark gray; (3) pink/red (4) white/yellow
Colors2: (1) green; (2) black (The colors are interchangeable, so you don't need a second Ace Pro)
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.
If you want to make sure you can print this design, download as trial the free platform module initial/end with barrier:
