This is a parametric version of the Gridfinity system by Zack Freedman. I have provided the Fusion360 files, one with just the parametric variables, and the other as a configured design. The configured design has many configurations already set up. I have also provided some STLs for common bin sizes, both stackable and non-stackable, as well as some baseplates.
I will be updating this design with more variations and sizes in the future so make sure to check back later so you don't miss anything!
