Recently I bought some Raaco storage drawers for cheap. While organizing my stuff in them I realized that the amount of drawer dividers that came with the drawers was insufficient.
While buying additional dividers is quite cheap, I didn't have the patience to wait for them and decided to print them instead. They print quite fast and fit well.
I included the FreeCAD project file. The models are parametric so it should be pretty straightforward to add other sizes.
I printed them in PLA with 0.2mm layers to ensure that the thickness was accurate. Due to my existing top/bottom layer settings they ended up solid, so infill settings did not matter for me.
The author marked this model as their own original creation.
