This model still works perfectly fine, but I have redesigned it with faster printing time and less filament usage, and dovetail connections rather than pins. The 2.0 Model can be found here:

I wanted a nice way to store filament upright in the Ezy Storage18L/19Qt Waterproof Clear Latch Tote IP-67 from Home Depot, so I designed this modular stand to hold a infinitely variable number of spools nicely in a row. It just so happens I designed this to fit 4 across perfectly into the waterproof storage tote I bought, but it's universal and modular. 

All you need to do is print 2 of the symmetrical ends and as many middle pieces as you need to display or store as many spools of filament as you want. 

I also created 2 alternate middle pieces, one that holds a round hygrometer similar in dimensions to the one Bambu sells, as well as one that holds a rectangular hygrometer again similar to the dimensions Bambu sells. Those are on build plate 2, you don't need them, you can mix and match as many different middles as you want, as long as you have 2 of the symmetrical ends printed.

The pins should fit snugly enough for storage, but if you want some extra security a few drops of super glue on the pins should suffice.
