Worked on enhancing the Rotor LOX Bearing Nut Tool design within the PURPL-Purdue/Turbopump repository, focusing on improving its functionality and fit for the rotor assembly. Applied CAD modeling and mechanical design skills to update the design file, ensuring better integration readiness and reducing the likelihood of rework during assembly and testing. Maintained a clean, auditable commit history to support traceability and documentation of CAD changes, with explicit file naming and commit references. The work emphasized careful version control and clear documentation practices, leveraging CAD tools to deliver a targeted feature that addressed assembly compatibility without introducing new bugs.
