I keep my filament in ziplock bags and store them in plastic boxes. I have tried everything I can find at Walmart but have not found the perfect size. I made a 10mm extended latch and some 10mm side extenders so 5 standard spools fit in vertically. I also modeled a standard size latch incase you just need a replacement latch.

This box is NOT air tight. It is just so you can stack boxes on the shelf and organize your filament.

I made my latches from PETG and used support only on the hinge tabs. I blocked support on the latch dimples at the top because the support would fail before it got to the top.
The side and end extenders can be pla. I glued the extenders with rubber cement but silicone glue would work better.
