Extreme Compact Spool Rollers

Compatible with all 1kg spools from BambuLab, including all existing variants. Some spools may fit slightly looser. In the future, I will add rollers for 250g and 2kg spools to create a more compact system.The 8mm smooth or threaded rods are essential components, providing the rigidity and stability needed for this system.
