Mazzer Mini Funnel for single dosing

This funnel has been rebuild but the idea came from https://www.thingiverse.com/thing:2641442
Thank you for this design "hell_engineer"

If rebuild it, because I wanted to have a sturdier design, as I tab on the top of the funnel to blow retained coffee out of the mazzer mini. With the version from "hell_engineer" I destroyed the funnel after some days (probably my fault).

Have fun.
