Porta filter funnel for Breville coffee grinder

I needed a funnel that fit the porta filter on my Breville BCG820CRNXL "Smart Grinder". This is the result. Pretty simple design, probably similar to several others that fit other grinders, but I started from scratch, so this is not a rework. I started with a smaller funnel that snapped inside the porta filter, then redid it so it clips on outside and allows the tamper to pass thru without restriction. I tried both PETG and PLA Carbon Fiber to print this, both seem to work equally well.

I hope someone else finds it useful.
