Blind Shaker/Dosing Cup for 40mm Portafilter

Blind Shaker/Dosing Cup for the 40mm portafilters used on the Flair Neo Flex. No more struggling to get grounds from the grinder into a funnel while fighting clumps, getting grounds on your scale, and having a lopsided mound that needs to be distributed. Dump your grounds in this thing while on the scale, place it on your portafilter, lift and shake the stem, then tamp for the cleanest packed portafilter.

The original design called for .12 layer thickness to minimize grounds being caught between layers. 2 layer walls (shells) are great, but if you are going to travel with this, I'd go with 4 layers or more. Use whatever infill you like…Though we will judge you silently.

This remix changes the geometry of the cup's base to have it sit over the Flair Neo Flex's portafilters and allowing the tamper to tamp while the cup is in place. Small modifications had to happen to the stem and the cap as well.
