Not sure how much interest there is in this but thought I'd share anyway. Originally designed with the intention of using a OE mini hopper but then I printed out a mini hopper so I could test the stability of the adjustment ring during grinding. Still on the fence on which way to go. Fits ~38g of beans as is and will be used with weight based dosing (arduino/load cell) that's about 50% done. Goal is to just load up the mini hopper and then hit grind to get what I need for the pourover.
