During February 2025, contributed to the KittyCAD/kcl-samples repository by delivering a visual appearance enhancement for the walkie-talkie model. This work focused on improving visual fidelity and customization by adding color to key components such as the antenna, body, and buttons using 3D modeling and CAD techniques. Leveraging the KCL language, introduced standardized appearance definitions to ensure consistent theming and easier customization across models. The enhancement was documented with a traceable commit and linked to a related issue, reflecting a methodical approach. The contribution addressed the need for more visually distinct and customizable models, emphasizing maintainability and clarity in design.
