A slight remix of a nozzle box I found here on Thingiverse. Original held 50 nozzles. Mine holds 30. I edited the lid a little so I could print it in two colors to make the design pop a little more and turned the design 90 degrees. Added a flat bottom to the insert for better bed adhesion. I did 100% infill on the box and lid. The inserts I only did 10%

2.0 updates: Made the border on the lid a bit more prominent. Added outer border to the lid to make it more complete looking. Added a long nozzled option to fit my Volcano nozzles.

Fun side note: The insert that I printed with a 0.4 nozzle left the nozzles loose and easily removable. The insert that I printed with a 0.6 nozzle made the holes perfectly sized so I have to screw in the nozzles. I prefer the tighter fit for security, but you might not.

The original designer recommends .2 resolution. I printed mine at .08 because they're pretty tiny. Each piece still took under an hour at that resolution
