Laser Shaft Alignment Tool

Generate a valid 3D-printable model using OpenSCAD. IMPORTANT OUTPUT RULES: - Output exactly ONE fenced code block using the openscad language tag. - Put the complete OpenSCAD script inside that code block. - Do not include any explanations or text outside the code block. - Use valid OpenSCAD syntax and ensure the script can render. PROJECT: Laser-Based Shaft Alignment Tool. Create a simple educational 3D model with these dimensions: 1. Base plate: 300 mm × 100 mm × 15 mm. 2. Left DC motor housing: cylinder, 40 mm diameter and 50 mm long. 3. Two horizontal shafts: 6 mm diameter, positioned along the same axis. 4. Flexible coupling: cylinder, 12 mm diameter and 20 mm long, connecting the shafts. 5. Two shaft-support blocks: 25 mm × 25 mm × 30 mm, with holes for the shafts. 6. Right pump housing: blue cylindrical housing, 45 mm diameter and 45 mm long. 7. Laser holder: small vertical bracket mounted near the shaft assembly. 8. Target board: vertical rectangular plate, 60 mm × 60 mm × 3 mm, positioned in front of the laser. Arrange all parts on the base plate. Keep the shafts horizontal and aligned along the X-axis. Use separate OpenSCAD modules for the base, motor, shafts, coupling, supports, pump housing, laser holder and target board. Use simple geometric shapes, appropriate colors and realistic proportions. Keep all components within the overall base dimensions. The result should be a complete static 3D educational assembly. Do not add animation or claim to simulate shaft motion.

Parameters

Every value above is a live dimension. Open a model like this in the editor and each one becomes a slider you can drag before exporting.
