Supersilent Knockbox

Everyone in your household has different waking hours and you or your roommates are         annoyed by the early birds making their coffee?

There is a solution, no bam-bam-bam at 5 a.m., just use the supersilent “knockbox”.

Print it, put it into your kitchen and enjoy your silent mornings.

When in need to clean the sieve of your portafilter machine, just put it upside down onto the supersilent knockbox and turn it a bit left and right until the cooffee grounds are released into the box.

For 52mm portafilter sieves

Modell A, the version that you find in the enclosed pictures is made of Prusament PETG Matte Black with 0.2 mm   layers on a Prusa MK4S. It has been tested with my Kenwood portafilter machine.

Modell B should fit for most other portafilter models (but has not been tested).
