3D CAD for Robot Mechanism Design

3D CAD Design – Motorized Vertical Z-Axis Lift

I’m looking for a mechanical CAD designer to develop the 3D CAD model and manufacturing drawings of a motorized vertical Z-axis lifting mechanism for a mobile wall-finishing robot.

Requirements:

2,000 mm vertical travel
60 kg design payload
48 V DC motorized lifting system
Lead screw + linear guide arrangement
Motor, gearbox, bearings, coupling, brake/holding mechanism
Vertical structural column
Moving carriage
Robotic-arm mounting interface
Mobile robot base mounting interface

I will provide the complete concept, rough sketch, dimensions, engineering calculations, load cases, component specifications, and design approach. You do not need to perform the engineering calculations or redesign the mechanism.

Your scope:

Convert my concept into a clean, fully editable 3D CAD assembly
Model all custom parts and integrate purchased components
Check clearances/interferences and assembly feasibility
Create manufacturing drawings for custom parts
Create assembly drawing + exploded view
Prepare BOM
Provide native CAD files + STEP files

Preferred: SolidWorks / Fusion 360.

Looking for someone experienced in mechanical machinery, robotics, linear motion systems, and manufacturing-ready CAD design.

Please share 2–3 examples of similar mechanical/robotic CAD projects you have worked on.
