Knockbox for Espresso machine

Simple and stylish knockbox to empty the filter holder of an espresso machine. Sized perfectly for the Sage Barista Pro (54mm portafilter)

The 20mm diameter wooden dowel is a friction fit in the slit so it doesn't rattle but can be easily removed for cleaning. I recommend printing with a larger diameter nozzle to speed up the process, with a 0.6mm nozzle it took about 5 hours to print.
