Parametrical BoxInBox Storage Organizer/Separator

I found myself a bit overwhelmed after ordering 60pcs of 43x43x20mm jewelry boxes off of AliExpress, and discovering they had no “general” organizer box.I tought about printing the entire box, however determined that it would be quite expensive both in time and filament use, for something so simple.Thus I opted for a parametrical separator design, which allows a multitude of small boxes to be stored in bigger boxes in an organized and clean way. The one in the pictures is an old box from an Arduino kit, which, after cutting off the side flaps meant to hold the original separators, resulted in a perfect snug fit for the provided 10x3 grid. The result looks similar to commercialy available organizers fit for this purpose, so i'm happy with the result.
