Press fit ring that attaches to the bottom part of the Slow Feeder (By Lee Taylor) and sets on the anti-popcorn ring of the df84v.

Anti-popcorn metal plate can be removed to allow the beans to drop directly.

The ring is made with small tolerances to make it sit firmly on the grinder (but I could make a second version with higher tolerances if someone ask for it).

Testesd on a prusa mk3s with prusa filament.

No need for support.
