Prusa MK2 spool roller

thingiverse

Here's a remix that combines the best features of The Ultimate Spool Holder and the default Prusa i3 MK2 arm spool holder. This spool holder is composed of four precision-crafted pieces, requiring four 608 bearings for smooth rolling action and four M3x30 screws plus nuts to secure them firmly together. The space between each arm is easily adjustable, accommodating a wide range of filament spools with ease.
