Parametric Gridfinity Pencil Tray

About this project This is the first model I’ve uploaded to MakerWorld and my first deep dive into OpenSCAD. I’m a computer engineer, and while organizing my art tools with the Gridfinity system, I wanted an automated way to handle different pencil and marker sizes without searching for a new model every time.I tried a few existing generators, but found them tedious or lacking specific features I needed. My goal was to build a solution that stops wasting filament—instead of bulky bins, this script generates "filament-saver" trays tailored exactly to the tool size.Version Historyv1.5 (Current): Added "Thin Wall" (1.2mm) presets for every tool. These print 30% faster and use less material while maintaining magnet retention.v1.4: Validated dimensions for Posca caps and rounded slot ends to ensure zero collisions.v1.3: Corrected base geometry to strictly follow the Gridfinity standard (1.8mm vertical wall).v1.2: Added precision M3 screw bores for weighted bases.The "Eas
