Parametric Coffee Funnel / Distributor! what else?

This device is intended to insure that your ground coffee powder is set uniformly before you tamper it.

Inspired from earl258's ["Coffee Distributor tools for espresso"](https://www.thingiverse.com/thing:2495288), I've redesigned it so that you can choose the different parameters using the Customizer app (clic on "Open in Customizer on the right).

I'm printing it using PET..
