The prompt
Refine this existing Prototype 2B design. Do not create a new architecture from scratch. Keep the same core system, but make the layout and appearance much closer to a polished engineering concept like a compact automated dispenser. MAIN GOAL: Transform the current rough white block assembly into a clear, detailed, visually understandable machine. LAYOUT TO FOLLOW: - six removable pods arranged in a rear semicircle - one central 6-port rotary selector valve in front of the pods - one single horizontal syringe pump on the right side - one fixed dispensing nozzle at the front/center - one receiving bottle directly below the nozzle - one load-cell platform under the bottle - one electronics enclosure in the rear-right area MAKE IT LOOK MORE LIKE A REAL MACHINE: - replace simple block placeholders with more recognizable engineering shapes - pods should look like clean removable cartridges - selector should clearly look like a rotary valve - syringe mechanism should clearly show: - syringe barrel - syringe plunger - moving carriage - two guide rods - one threaded lead screw - stepper motor driving the lead screw - nozzle should be clearly visible and fixed above the bottle - bottle platform should clearly appear to sit on a load cell TUBING: - show all 6 short pod-to-selector tubes clearly - show 1 short selector-to-syringe tube - show 1 short syringe-to-nozzle outlet tube - keep tubing neat, short, and realistic - no floating or disconnected tubes VISUAL STYLE: Add colors to make the machine understandable: - six pods = six different colors - the six pod tubes = matching pod colors - selector valve = dark gray - syringe barrel = transparent or translucent - plunger = white or light gray - lead screw = metallic gray - stepper motors = black or dark gray - base = light gray - electronics enclosure = dark gray - receiving bottle = transparent - load cell platform = medium gray ASSEMBLY QUALITY: - all components must be mounted and supported - no exploded view - no floating components - add brackets and holders where necessary - keep access to the pods and syringe for replacement/service IMPORTANT: There are only 2 stepper motors total: - Stepper 1 drives the rotary selector - Stepper 2 drives the syringe lead screw There is only 1 syringe pump. Do not create six syringe pumps. Do not create a rotating nozzle wheel. Do not create six peristaltic pumps. The final result should look like a compact, assembled, easy-to-understand prototype concept, not a rough white block model.
