Crankandstein Grain Mill Hopper Base

thingiverse

This is a grain mill hopper base that works with the 2D Grain Mill from Crank And Stein. I don't believe they make this model anymore as it seems to have been replaced by the 2DG model. I suspect it will work with the 2DG and others, but double-check the bolt spacing. This hopper base will allow you to use a 5 gallon Primo water bottle/carboy for a hopper on your grain mill. Updated 3/27/2023: GrainMillFinal.stl is the latest version. On the original design I measured wrong so the holes weren't spaced quite right. I also adjusted the height slightly so that I had proper clearance between the hopper and the 12" sheave that drives the mill. I printed the final version using eSUN PLA Pro (PLA+) with 90% infill density. That might be overkill on the density, but I wanted it to be strong.
