La Pavoni portafilter declumping ring

this ring drops into your portafilter for the post millennium La Pavoni (or the Gaggia Factory) so you can declump your grinds without using a cup etc.

it also fits under a Rancilio Rocky spout (and my easy clean spout http://www.thingiverse.com/thing:101392 )

not only that it works as a portafilter hanger on the grinder
