The prompt
Design a compact vertical Z-axis linear slide bracket for a Pick-and-Place machine head with the following specifications: 1. Envelope & Mounting: - Max body width: 22mm (to fit within a 20-24mm multi-nozzle inline pitch constraint). - Total travel stroke: 55mm. - Motor Mount: NEMA 11 stepper motor mounting face (28mm x 28mm frame outline) with four M2.5 threaded mounting holes on a 23mm bolt circle and a central 22mm pilot hole. 2. Linear Motion & Belt Mechanism: - Mounting provisions for a linear guide rail (MGN7 / MGN9 carriage mounting pattern) running along the vertical spine. - Drive mechanism: Timing belt pulley system designed for 0.5mm linear displacement per full step (100mm belt pitch circumference, e.g., 50-tooth GT2 pulley at 2mm pitch). - Pocketing and routing slots for a GT2 timing belt running parallel to the linear slide. - Integrated tensioner slot allowing 5mm of vertical adjustment for belt tensioning. 3. Features & Hardware: - Top and bottom mechanical endstop mounts for optical/microswitch limit sensors. - Pass-through mounting holes for M3 fasteners to attach to the main PnP head gantry. - Material/Design style: Lightweight aluminum or high-rigidity 3D-printed structure with 3mm minimum wall thickness and chamfered edges.
