Configurable 3D-Printed Calendar in OpenSCAD: Zeller's Congruence and Beyond
2025-02-14
A developer created a highly configurable 3D-printed calendar model using OpenSCAD. Leveraging Zeller's congruence for accurate day-of-week calculations, the model automatically adjusts date offsets. Users can customize rendered months, column layout, layer height, add custom holiday markings, and even include magnet holes. This project showcases OpenSCAD's power in algorithmic implementation and parametric modeling, supporting multilingual features and multi-material printing.
