Universal Filament Spool Dispensers
thingiverse
Since I wasn't satisfied with the progress of PLA filament, I made my own solution... not necessarily space-saving but 100% better. Cinema 4D demo version and MakerBot Replicator2 were used in this process. Items required include two cone rollers, a threaded rod M8, two 8mm inner diameter ball bearings with an outer diameter of 22mm, two 30cm hole sheets made of plastic material, six M8 screws, and two sets of M4x16 screws, nuts, and washers. Assemble them as shown in the images, and you're good to go! This setup is also possible for more PLA spools with longer threaded rods; tested successfully with various PLA spools since the inner diameters of rolls vary. The design was created due to varying inner diameters of different rolls, making this solution simple yet brilliant.
