Cunill Single Dose Hopper

thingiverse

This is a remix single dose hopper that will fit many type of Spanish made Cunill grinder. The hopper has a built in anti-popcorn insert. It's a bit hard to print it nicely because supports will ruin the nice surface but without support some of the features will be quite messy. I tried rotating the whole thing 45° in cura which produced nice surface areas but the bottom came out a bit ugly and uneven. I redesigned the dosing cup a bit keeping its outside but added a cup inside which ends in a 53mm ridge that fits perfectly into a 53mm portafilter. So the dosing cup can be used help measuring the coffee beans, collecting the ground coffee and empty it into the portafilter. The dosing cup doesn't require support of any kind.
