Coffee knock box

Knock box for portafilter machine I designed a knock box since my girlfriend didn't really like the old knock box we had. She really likes the new one (me too). Since I could use the old rod I did not need a new one. Nevertheless, I attached an STL file for you so you can print the rod as well. The "brackets" for the rod are specially designed so that it can be printed without any support (angle not greater than 45°). Since this is a functional part that has to withstand a lot, I printed with 5 wall thicknesses (2 mm thick in total).To shorten the printing time a bit, I chose a layer height of 0.24 mm and a 3D infill of 15%. The total print time on my Ender 3 V2 neo with 50/80 mm/s was 22 h 59 min.
