This text describes the parts and assembly instructions for a 3D printed RC car. Here's a breakdown: **Parts List:** * **Wheels (4):** Printed in PLA for best results, mounted to axles with M5 nuts (standard inside, lock nut outside). Red loctite on rear right wheel bolts. * **Front Axle Fixed Mounts (2):** Sandwich together to hold front bearings and M5x40 bolts. Print strongest material possible at 100% infill and 3 shells. * **5mm Flange Washers (2):** Placed between printed drive gears on rear axle for alignment and stability. * **15mm Washer (1):** Used on the left side of the rear axle to space the wheel from the chassis. * **9g Servo Mount (1):** Bolts to the frame and holds a 9g metal gear servo. * **Steering Rack (1):** Connects to motor mounts, allowing wheels to turn. Attach with thin wire or stiff paperclip to servo arm. * **Esc Mounts (2):** Secure ESCs tightly to the chassis. * **Optional Side Intake Covers (2):** Snap into M3 bolt holes on bottom plate and fasten with M3x8 bolts to the top plate. They house wires, keep dirt out, and direct airflow for cooling. * **2430 Motor Mount (1):** Holds 2430 motors using M2.5 bolts. Also holds rear axle bearings in place. Attach to bottom plate with bolts. * **Front & Rear Bumpers:** Printed for protection and impact absorption. Use strong materials like TPU or nylon filament for flexibility. * **Rear Drive Gear (1):** Connects to rear axle with M5 nut. Print PLA at 100% infill and 3 shells. Various sizes provided for different printers/materials. Install with a mallet and red loctite. * **Bottom Plate (1):** The base of the car. Can be 3D printed, laser cut, water jetted, or CNC machined from various materials. Cheap 1/8" plywood is recommended for laser cutting. * **Top Plate (1):** Secures all components and adds rigidity. Attaches to front wheel mounts and rear motor mounts. Also houses side intake covers. Similar to bottom plate, can be made with various materials and fabrication methods.
