Minimalistic spool
thingiverse
This parametric, minimalistic spool is inspired by CCphoto's "Another spool." It simplifies filament change and can hold a 5 lb roll at default size (better with half the roll). Compatible with Mendel printers for 20 lb rolls. Customizeable with variables for arm size, number of arms, bearing diameter, and rod diameter. Includes STLs for m8 rod and 608 bearings or m6 rod and R188 bearings, both with 3 arms fitting a Cupcake's platform. Assemble by printing the hub and desired number of arms, attaching with 9-12" rods, and use with most mounting systems designed for other spools.
