We are looking for an experienced CAD/Mechanical Engineer to update and optimize an existing set of technical 2D drawings and 3D models for a turntable chassis. The project is currently in development. You will be responsible for updating specific dimensions and converting a multi-layered plate design into a single, solid component optimized for 3D CNC milling.
1. Dimensions & Geometry:
• Update the new outer dimensions to 440 mm width x 385 mm depth.
• Shift and scale internal dimensions proportionally (making them slightly larger) to match the new outer dimensions.
2. Component Integration:
• Add recess zones and screw holes for 3x round dampers and 2x feet (must accommodate 2 different types of footplates).
• Prepare mounting/hinge attachment points for an optional dust cover.
• Add specific cable routing channels and exit holes for external connections.• Integrate a standard tonarm fixed to the top plate.
OPTIONAL: The structure must allow for modular upgrades (detachable arm) in future versions (v2.0 / v3.0).
3. CNC & Thermal Optimization:
• Current State: Components are currently drawn as individual, stackable separate plates.
• Target State: Convert the design into 1 fully integrated component made from a single solid block of material, fully optimized for 3D CNC milling.
• Layer Management: This single solid component must be added to the main assembly drawing, but the independent/individual plates must remain available as separate layers/drawings within the files.
OPTIONAL: Thermal Management: The bottom plate cannot be completely closed due to heat dissipation from internal components. You will need to implement smart ventilation slots or openings.
Required Deliverables:
• PDF: For internal review and client verification.
• DWG / DXF: Updated 2D drawings with revised dimensions.
• STEP (.stp): Full 3D model of the integrated solid CNC component.
Project Structure & Milestones:
Since we need to sync and validate these dimensions with our end-client, this project will require multiple evaluation and feedback moments. Milestones will be released progressively:
• Milestone 1 (Revision 0.1): First draft of new outer/inner dimensions & spindle center.
• Milestone 2 (Revision 0.2): Integration of dampers, feet, cable exits, and tonearm prep.
• Milestone 3 (Final Revision 1.0): Solid CNC model, total assembly sheet,
OPTIONAL : extra mile stones
Freelancer Requirements
• Proven CNC Enclosure Experience: You must have demonstrable experience in designing enclosures or complex components milled from a single, solid block of material (fully accounting for CNC tool reach, clearance, and minimum radiuses).
• Timeline Estimation: You must provide a clear and realistic time estimation for both the first draft (Revision 0.1) and the final delivery, factoring in the required review moments.
• Revision Flexibility: You must be fully aligned and comfortable with a structured workflow that includes 2 to 3 iteration/revision rounds based on feedback from our end-client.
