I wanted something that worked well to hold my working pen nibs (the ones that aren't used yet are in a separate container). An Altoids tin seemed perfect, but I didn't want a big pile of them in the tin; I wanted something neater. I remixed and combined SylvainKlein's Calligraphy Nibs Storage and bill de_cat's Altoids template to create something that would work for me!
Filament I used:
Prusament PLA Galaxy Silver
