Mihai Oltean used OpenSCAD to design a full vertical pepper garden, writing code to generate a parametric 3D model of the entire wall structure before building a single physical part. No electronics, no automation. Just OpenSCAD applied to a problem nobody had apparently tried it on before.
The code, published on GitHub under the wall-garden repository, skips standard parts libraries like NopSCADlib entirely. Oltean implemented his own virtual screws, nuts, washers, and metal extrusion sections from scratch. The model was never destined for a 3D printer or CNC machine. It was a planning tool, used to verify how all physical components fit together before committing to hardware.
The original article is worth reading for one specific reason: it makes a clean argument that virtual-first CAD workflows belong outside the electronics workbench. Two weeks prior, Hackaday covered the same technique applied to a CNC control cabinet. This project extends that logic into raw physical construction. If you build anything with more than a handful of interconnected parts, the methodology here applies to you.
