Those look a lot like the cases the local hardware store sells.
I keep at least thirty kits in a spare fridge. I like how the original cases are see-through and let me put a full label on top, but they end up scattered across the shelves. I already have cases for single vials, yet pulling them out every time makes checking labels and tracking stock annoying. I want something that holds the kits while they are still in their factory packaging. I came across a style on a marketplace site that fits up to sixteen kits and also has a spot for desiccant packs. If anyone here prints in 3D, would it be simple to make something similar?
