Melitta Coffee Grinder foot

A foot tore off my trusty old Melitta burr coffee grinder and the wobble has been annoying me every morning for quite some time. Today, it dawned on me, this would be the perfect thing to test out flexible filament though my v2 extruder.

Note: I'm not sure if this will fit the newer Melitta burr grinders. I bought mine (model: MEM1B) new back in 2003 as a closeout from shopnbc.com for $4.96 delivered! They fit snugly into the 8.5mm diameter holes.
