Breville Coffee Grinder Impeller Replacement - Type 2

thingiverse

Updated Jan 1 - Will Print Better Different version intended for coarser grinds, but definitely should work great with fine grinds as well! I mostly use french press, and found that my first replacement impeller didn't work well with coarser grinds, it didn't seem to be able to clear them consistently, but did work great with fine grinds. I noticed the original impeller had straighter blades, so I incorporated that into this Type 2 revised design: - Type 2 V2.0 Impeller now offers 727mm^2 of area for grounds, while the V2.0 Impeller only offers 600mm^2. That's 21% more room for grounds! Should handle coarser grinds with ease. I tried to reduce arm count, but only gained minimal returns. I may try a different design altogether if I still have issues, but I doubt it.
