DF64 offset 58mm portafilter holder

This is a portafilter holder designed specifically for the DF64 coffee grinder that has been modified with some other upgrades. It might work fine on a stock DF64, but I made this for our specific application and it works AWESOME for that.
I've updated this design to have thicker lower arms as the thinner ones had a tendency to break after a while. I also tightened up the tolerances a little.

DF64 coffee grinder modifications that led to this design:

- DF64 input flow regulator (by Gary McCormack: https://grabcad.com/library/df64-input-flow-regulator-1).

- DF64 Exit chute and downspout (by Gary McCormack: https://grabcad.com/library/df64-exit-chute-and-downspout-1), we only use the large aperture chute and removed the declumper screen.

- DF64 iswitch (https://www.etsy.com/listing/1172855506).

We use a 58mm naked portafilter from Amazon (https://www.amazon.com/gp/product/B06ZZ24BH2) and an olive wood magnetic funnel from NepoCoffee on Etsy (https://www.etsy.com/listing/1014235116). I'm mentioning this because I made the holder to clear the funnel (hence the diameter difference between the lower and upper arms).

The holder is offset because the chute without the declumper tends to drop the grounds to the right of the portafilter.

The holder has a cutout for the DF64 iswitch, though I imagine it'd work without that switch, or the cutout can be filled. The switch allows for enough adjustments to fine tune when the grinder gets activated by pressing down on the poratfilter handle.
