The prompt
Refine ONLY the syringe-pump subsystem. Do not modify the pods, selector valve, bottle, load cell, or electronics enclosure. Replace all rough block placeholders in the syringe section with a detailed engineering mechanism: one horizontal 5 mL syringe barrel, fixed in a removable cradle one syringe plunger extending rearward one moving plunger carriage that grips the syringe plunger flange two parallel 8 mm guide rods supporting the carriage one central T8 lead screw, 8 mm diameter, parallel to the guide rods one brass lead-screw nut fixed inside the moving carriage one NEMA 17 stepper motor directly aligned with the lead screw one flexible shaft coupler between motor and lead screw front and rear lead-screw bearing supports two limit-switch mounting points at the ends of carriage travel realistic M3/M4 mounting brackets and screw holes The syringe barrel must remain fixed. Only the plunger carriage moves. The mechanism must clearly show: Stepper motor → coupler → threaded lead screw → moving carriage → syringe plunger. Create all parts as separate editable components and use realistic dimensions and spacing. Eliminate floating parts and vague blocks.
