3D Handshake Relief CAD

I need a clean, production-ready 3D model of a 300 × 200 × 30 mm aluminium plate featuring a deep-relief (11–15 mm) handshake in the centre. The hands must look highly realistic, with individual fingers, skin folds and neat shirt cuffs, sitting on a recessed background framed by a raised outer border.

The file has to be fully machinable on a 3-axis VMC, so please keep every surface draft-friendly and avoid undercuts. Once complete I will run the model straight into CAM, so STEP format is mandatory.

Deliverables
• Final STEP file of the full plate
• High-resolution renders for approval before hand-off

When you reply, include two or three images of similar CNC relief work you have done, along with your price and the time you need to deliver the finished STEP.
