A hinged top box

I needed some boxes to hold tiny items that I could store stacked so I drew these up they are outer dimensions of 100mm L 40 mm W 40 mm H. I included a hinged top that uses a piece of 1.75 filament as a hinge pin, which I melted a ball on the ends as keepers. you can print labels to identify the contents but I just wrote on them with a sharpie.
