Do you have many filament rolls but limited space?
Use the Multi Material Spool!
Now you can keep all your left over filament without getting annoyed by your huge storage of old rolls!
Comes with three different spacers for your convenience. You can store two, three and even four different materials on the same spool! And there's more, you can combine them for even more fun!
Print center, nut and as many sides and spacers as you need.
Attach the filament at the center of the spool by a zig-zag through two or more of the holes.
Transfer your filament.
Lock the free filament end by threading it through two of the holes at the edge of the side. Make sure it ends up inside it's own compartment, trim the end if necessary to avoid risk of snagging on the other filaments.
The medium spacer gives three compartments.
The diameter of the side is 190mm so it should be printable on most printers.
Three perimeters, three bottom and three top layers gives PLA parts that are stiff enough to use. 25% infill.
No need for supports.
