I designed this box after ordering a bunch of colored ribbon and they arrived with no sides to the spools resulting in huge mess when I tried to use one. This box at its set size is 9 and ¼ inch long by 4in wide and with the ribbon inside stands at 4 in tall.it fits 18 of the ribbon I made it for but it can be altered to fit whatever spools you need. I also added a hole through the whole center to allow a dowel for easy use.

i used Xyz “natural” colored filament for mine and it took 6.5 hours to print on my A1 at standard speed.
