I was sorting a bunch of stuff into Tactix 4 box modular storage containers, and needed a way to add more sections to the boxes.
This splits each section into two, and is completely removable.
It will fit in the middle sections, and the ones across the back - but not the corners.
It has a radius in the bottom, to make it easier to scoop small parts out with your fingers.
The author marked this model as their own original creation.
