Ergonomic Controller - Parametric Shell & Grip Study

A two-handed controller concept developed with editable lofted shells and three grip configurations. Exploded and section views show the internal tray, controls, screw bosses and assembly arrangement. The project includes editable FreeCAD models, STEP/STL exports and drawing documentation. It demonstrates product enclosure modelling and configuration comparison. This is a digital design study; comfort and physical fit require prototype evaluation.
