This is a precision-designed spool insert specifically engineered for seamless integration with my trusty Wanhao I3, ensuring a silky-smooth operation of the spool. Measuring precisely 31 mm in inner diameter to perfectly fit the stock spoolholder and an impressive 51 mm in outer diameter, this expertly crafted component is designed to optimize performance. With its clever design featuring two easily assembled halves that securely screw together, I can count on reliable and efficient operation every time.
