Portafilter small Knockbox

This knockbox was designed with the intention to use the metallic cylinder of a knockbox I bought a few weeks ago. The size of the cylinder is 140x25Ø mm. I included a replica of the cylinder in the print, if you don't have one already, but I think a metal cylinder works so much better than a plastic one, whatever the material or the infill you print it with.I made this knockbox because:- The original bin was open, this one has a lid. So you don't need to empty it after every use;- It has a square base, instead of a circle one. Better to place in my kitchen;- The cylinder doesn't drop after every hit… Print the bin in PETG, and the lid in PLA (you can set a second color for the logo, I used a silver filament and it's pretty cool).
