The prompt
3D Modeling & Print Request: Mechanical Control Lever Assembly Design Concept & Style - Object Type: A retro-industrial mechanical control lever (throttle/joystick) styled similarly to a ship or locomotive console control. - Components: A two-part snap-fit assembly consisting of a Control Lever and a Black Box Base Enclosure. - Aesthetic: Clean, utilitarian design with smooth rounded edges. The main body consists of a dome-like metallic silver base cover, a central shaft, and an ergonomic curved black knob handle at the top tip. Mechanical Specifications & Functional Constraints - Toolless Assembly: The design must feature a completely glue-free, tool-free snap-fit (click-together) joint system. The lever pivot rod must securely click into the interior retaining brackets of the base box without loose play. - Range of Motion: The lever rotates strictly along a single horizontal axis. It must be capable of rotating 45 degrees to the left (halfway) and 45 degrees to the right (halfway) from its upright center position. - Hard Stops: Incorporate robust, thick internal physical stopper walls inside the box housing that securely block the bottom toggle mechanism, preventing the lever from rotating past its 45-degree left/right limits. 3D Printing Optimization (Strength & Ease of Print) - Printability: Designed completely optimized for FDM 3D printing. All mating parts must feature clean 45-degree or 60-degree angles to completely minimize or eliminate the need for print supports. - Structural Integrity: Heavy mechanical joints must be thickened with generous fillets to withstand repetitive force during usage without shearing. The snap tabs must have enough tolerance (around 0.2mm) to deflect and lock cleanly without breaking during initial assembly. - Base: A rigid, blocky black box foundation providing a wide footprint for stability during lever operation.
