The prompt
Create a complete 3D CAD assembly of a motorsport sequential shifter conversion for a 2026 Chevrolet Onix 1.0 Turbo with a 6-speed manual transmission. The design must replace the original H-pattern shifter while keeping the original factory shift cables and cable attachment points. Requirements: - Sequential operation only. - Push forward to upshift. - Pull backward to downshift. - Six forward gears plus reverse. - Reuse the two original transmission cables. - Original gearbox must remain unmodified. - Track-day use only. - Short and precise shifting. - Mechanical indexing system with ratchet and anti-return pawl. - Neutral and reverse lockout system. - Adjustable spacer plate between the floor and shifter base to modify shifter height. - Exposed racing-style mechanism without center console. Include: - Main shift lever. - Main pivot shaft. - Indexing wheel. - Ratchet pawl. - Anti-return pawl. - Springs. - Selector cam. - Cable actuator arms. - Reverse lock mechanism. - Neutral lock mechanism. - Structural housing. - Cable brackets. - Bearings and bushings. - Mounting base. Materials: - Housing: 7075-T6 aluminum. - Lever: chromoly steel or 6061-T6 aluminum. - Indexing wheel and shafts: heat-treated 4140 steel. - Bushings: bronze. - Springs: spring steel. Generate: - Complete assembled 3D model. - Exploded view. - Internal mechanism visible. - Motorsport-style industrial design. - Manufacturing-ready components.
