Breville Coffee Grinder Impeller Replacement - Type 2

thingiverse

Updated Jan 1 - Prints Better Now\r\n\r\nDesigned for coarser grinds, this impeller version also works great with fine grinds! I primarily use French press and found that my first replacement impeller struggled with coarser grinds, failing to clear them consistently, but performed well with fine grinds.\r\n\r\nI noticed the original impeller had straighter blades, so I adapted that design in this Type 2 revised version:\r\n\r\n- The new Type 2 V2.0 Impeller offers 727 square millimeters of area for grounds, a 21% increase over the V2.0 Impeller's 600 square millimeter capacity. This should handle coarser grinds with ease. I attempted to reduce arm count but achieved only minimal gains. I might try an entirely different design if issues persist, but I'm not concerned.
