Adjustable Filament Holder (which may also be used as pulleys)
cults3d
The filament holder that came with my UP! Plus printer didn't quite work for me because I have got so many different filaments sourced from different suppliers, some spools are thicker with smaller holes and some spools are thinner but with bigger holes. I searched on Thingiverse to find a new filament holder that'll suit all these different spools, but there were only 2 adjustable ones I could find. I decided to design one myself that I can print in one go without any assembling. I've replaced the filament guide to this one I found on Thingiverse (http://www.thingiverse.com/thing:31961) because the original filament holder/guide from UP was in one piece.
