Portafilter Cleaner

Maybe you know the situation:

You slam your portafilter with passion onto your coffee bucket. Suddenly your neighbour rings the door bell and starts yelling at you. You tell him it´s three o´clock in the morning and maybe there are people, who want to sleep. You wish, but can´t for two days now...

Give your neighbour the present of sleep and drink your espresso quietly by printing this awesome cleaning tool.

And always remember: the more caffein you have in, the louder and faster you´re able to play your trumpet.

The diameter is nearly 48 for the bottom and 58 for the top. It should fit the stock portafilter for the Rancilio Silvia. For all the other sizes feel free to tweak the f3d-file.
