Developed foundational CAD infrastructure for the fan adapter feature in the FE12_CAD repository, focusing on creating base parts and test assemblies to support rapid prototyping and validation. Leveraged skills in parametric modeling and assembly design using CAD software, establishing a testable baseline that enables iterative design reviews and future integrations. The work accelerated the readiness of the fan adapter by reducing downstream risk and supporting agile development cycles. No major bugs were addressed during this period, as efforts centered on initial feature delivery and scaffolding. The approach emphasized maintainability and extensibility, laying groundwork for ongoing CAD development and collaboration.
