Single dosing hopper for Eureka Zenith Coffee Grinder

prusaprinters

The Eureka Zenith coffee grinder has a massive hopper intended for commercial use with multiple kilos of coffee being in the hopper at any given time. Using it as a single dosing grinder has two main issues: it's extremely unwieldy, and is prone to have retention.Like a fellow maker here on Printables who created a single dose hopper for their ECM S-Manuale, I created this hopper to fit the Eureka Zenith's original hopper opening. The dimensions are also based on the size of the MOAB bellows which is recommended to minimize retention. For those who are unable to print the MOAB (since it should be printed with TPU), I've also included a loose-fitting lid to prevent popcorning. The tolerance is 0.15mm to ensure it will fit. I've included the Fusion360 file if you want to reduce that tolerance.Prints very well in PLA, no supports required. <20% infill needed and you can print either right-side up or upside-down. For those with a textured PEI sheet, I suggest printing the lid upside-down so that the textured side will face outwards.
