The prompt
Create an editable 3D CAD concept assembly for a hand-cranked mechanical device that travels upward along a stationary rope. The concept has three rollers arranged with two rollers on one side of the rope and a third roller centered between them on the opposite side. Include a hand crank, reduction gearbox, synchronized roller shafts, bearings, and a two-plate frame. Keep each part as a separate component. Make roller position, roller diameter, shaft spacing, and frame dimensions adjustable. Show the rope path and check for collisions during rotation. This is a non-human-rated research concept. Do not assume that the rollers can safely grip a load-bearing rope. Do not represent the design as safe for lifting people.
