The prompt
2. Motor Mounting Brackets Create a separate motor mounting bracket at the end of each of the three arms. Each motor mount must include: A flat mounting plate for a small brushless motor. Four equally spaced motor bolt holes. A central motor shaft clearance hole. Additional bolt holes/provisions for attaching the motor bracket to the arm. Lightweight construction. Rounded edges and fillets. The motor mounts must be separate CAD parts that can be assembled to the arms.
