These are dividers for Sortimo T-Boxxes, the same Adam Savage raves about in his Youtube channel. I wanted to have more of them since the distributor I got acess to doesn't sell a box full with 1x1 containers, and I cannot seem to find them for sale anywhere.
I've uploaded single and double dividers in two versions.
It is important to notice 3d printed dividers lock to each other very strongly!
To have a better experience, I recommend printing the single divider with a .20 layer height, and the double with either .16 or .24. Then they don't lock as hard to each other's layer lines.
