Nozzle Bin
This thing was made with Tinkercad. Edit it online https://www.tinkercad.com/things/2E5SqWjffqI
Did design it with a bit of tolerance between the outer and inner shell so it should fit snuggly but not be too tight. I ordered a bunch of nozzles of different sizes for my Ender 3 and wanted a closed bin to hold them in so designed this.
