Baratza Vario parametric portaholder

I wish I had coffee grinds filament for this one ... [Baratza Vario](https://www.amazon.com/gp/product/B0027DVMDC/ref=as_li_tl?ie=UTF8&tag=mgx3d-20&camp=1789&creative=9325&linkCode=as2&creativeASIN=B0027DVMDC&linkId=9cddad2b6154712f7d073be034dc6406) 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.
