Hello! This is so helpful. I plan to print the squared ones soon. Did you ever find a solution for storing the 3700 boxes? I'd be interested in that, as well. Thanks!
The short term plan was to build a simple shelf system to hold them. I cut some scrap wood to width, then got distracted by other projects. Long term I'd like to find an affordable way to make slide out drawers for them. Having to stack and unstack them is getting old.
