What started as repair for a high-end coffee grinder turned into an improved portaholder that 3d prints in one piece. I wish I had coffee grinds filament for this one ...

Baratza Vario is such a nice coffee grinder but the portaholder it came with was ... less than ideal: spreads coffee everywhere, requires both hands to operate and it breaks easily.

So I designed a new one. The STL here is for 58mm Breville portafilter, but you can open the script in OpenSCAD and adjust for a tight fit for a variety of other portafilters.

Features:
the portafilter fits in tightly now, doesn't let coffee grinds fly all over the kitchen
you can leave the portafilter in the holder (one handed operation)
you slide out the portafilter and this makes the coffee come out evenly spread
it snaps tightly into the Baratza Vario notches
I debated whether I should add a tray at the bottom or not (because there will still be coffee or water drips) but in the end decided to save plastic
