When using the ELEGOO CC2 3D printer, have you encountered this common issue: the spools of FDM filament available on the market often have a center hole that is too small, making it difficult—or even impossible—to properly mount them onto the printer’s original spool holder? This seemingly minor dimensional discrepancy can significantly impact filament feed and overall print reliability.

To address this practical pain point, I have specifically designed this CC2-specific external roller attachment. It is not a complicated modification; rather, it is a simple, direct, and highly compatible enhancement component.

Key Advantages

• Perfect Compatibility: Designed specifically to match the CC2’s frame structure and interface, ensuring a seamless, stable, and reliable installation.
• Addresses the Core Problem: The roller’s diameter has been carefully optimized to easily accommodate most standard and non-standard filament spools on the market, effectively eliminating the “cannot be installed” issue.
• Ultra-Simplified Design: Features an integrated printing design that requires no additional support structures. Simply print the component using a strong material such as PETG or ASA, locate the corresponding screw holes, and secure it with the printer’s original screws. The entire process takes only a few minutes and requires no extra tools or complex assembly.
