Coffee Grinder Mini Hopper

Mini Coffee Grinder Hopper -

So you are a coffee freak! own a coffee grinder, build you own coffee recipes, improving you barista skills.
But how are you testing all these coffee blends with only one original grinder hopper? Need to remove blend A beans from the hopper, replace it with blend B beans, write down recipe details on your notebook…(..fogot what blend is in my hopper now...)

The mini coffee hopper was my solution, 3D printed couple of mini hoppers, each hopper holds about 3 doses of beans. I label each hopper with the coffee type and recipe details..
