Parametric Under-Shelf Storage Rail System

I am currently learning Fusion 360 and wanted to design a fully parametric model that is actually useful in everyday storage setups.Since I could not find a configurable slide-in rail system for hanging storage boxes, I decided to build one myself. My goal is to allow a precise adaptation to different box geometries, shelf thicknesses, and load requirements - I only could find fixed dimensions on Maker World. Feedback is very welcome — I am actively trying to improve the design. After adjusting the parameters, simply download the model and duplicate the rail segments as needed in your slicer. T-connectors for mounting multiple box rows side by side are currently in development.
