Baratza Vario parametric portaholder

I wish I had coffee grinds filament for this one ...

Baratza Vario is such a nice coffee grinder but the portaholder design is ... less than ideal: makes a mess everywhere, can't hold the portafilter by itself and breaks easily.

I designed this portaholder with a funnel for my 58mm Breville portafilter, but the design is OpenSCAD parametric and can be adjusted for a tight fit for a variety of other portafilters.

Features:

• the portafilter fits tightly, 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 and print time.
