I have seen many 3D-printable organizer systems featuring complex mounts and modular designs. However, after calculating the costs, I found that purchasing a commercial solution is far more economical in terms of both time and resources. 

Furthermore, I didn't want to discard the boxes and containers I already own. In practice, I usually opt for repurposed containers or standard bins that fit my shelving, though these often lack the necessary internal divisions.

This led to an idea. I frequently print small test cells for calibration purposes and use them for storage. I realized I could design custom grid inserts for my existing containers.

I have developed a parametric 3D model that allows users to input the dimensions of a specific area and define the required number of cells.



The result turned out excellent, so I am sharing it here in case anyone finds it useful.








📌I recommend setting the wall thickness to a multiple of your extrusion width. For smaller cells, I typically use a thickness of two perimeters; for larger ones, I suggest using three or more.
