As stated above, the first few M3D Crane printers did come with a 3D printed spool holder, which was designed to hold all 4 of the smaller CMYK filament spools. This design has been upgraded but the 3D printed spool holder is NO LONGER included in the box with the printer. We DO have the STL file for the updated spool holder design. We suggest you download the STL, slice it, and print it to your own specifications.
