This is my version of 3D printer drawer dividers with parametric sizes and a system of connecting them using lego-like pieces with pins.
I am using OpenSCAD to develop the system and generate the STL, PrusaSlicer to generate the GCode, my script 3MF-zip-dir to convert the PrusaSlicer project file to a directory (so it is fit for version control) and Prusa MK3S to 3D print the parts.
