Prusa Spool Box
thingiverse
A lot of people out there received a free filament spool with their Prusa i3 MK2(S). Consequently many should also have an empty spool of said filament. This idea was blatantly stolen from Matterhackers' Spool Tool Desk Organizer. The Prusa filament spools already have holes in them, so I just reused those instead of drilling new holes. You can use 1.75mm filament as rivets but 2.85mm filament works best. You'll need around 100g of PLA per 90° segment so 400g to complete the circle. It prints nicely with a 0.35mm layer height. I'm not sure where you'd use the tall boxes for, but I uploaded them regardless. Since the Prusa spool is very wide, in my opinion splitting each segment into three boxes makes more sense.
