Espresso Knock Box #2

thingiverse

This is a revised take on my initial concept. The primary problem I encountered with the first design was that my portafilter consistently came apart - the sieve would drop into the box. To address this issue, I redesigned the layout so that the sieve strikes the bumper directly. I've also included a tamper base that can be placed atop for resting the portafilter during the tampering process. This feature integrates seamlessly with Oricone portafilters.
