Alternative hub for loose filament Spool

youmagine

This is a modification of Woofy's Spool Holder for loose filament. Check out the design at https://www.youmagine.com/designs/spool-holder-for-loose-filament. Print 6 hooks and 6 arms from this design, then add the modified Hub. You may also want to print one or two spacers if you don't like how close the spool is to the wall where it's attached. This setup allows for mounting a spool on an alternative holder, such as lRobertl's low-friction spoolholder: https://www.youmagine.com/designs/low-friction-um2-spoolholder. Just keep in mind that loose filament holders are bigger than standard spools and won't fit on the back of the UM2.
