Handheld Electronic Safety Device Design

Hi, I am looking for a Product Designer / Industrial Designer to create a professional 3D CAD model of a small handheld electronic safety device.

This is NOT an architecture or 3D art project.
I need someone who has experience designing physical consumer products, especially small devices that fit in the hand.

You must be able to provide CAD files suitable for manufacturing.

Deliverables:
1. Full 3D CAD model of the device
(internal structure + outer shell)
2. Manufacturing-ready files:
• STEP
• STL
• OBJ
3. 6 high-quality rendered images
• Front view
• Back view
• Left + Right
• Top view
• 3D perspective
4. Basic internal layout
• Space for speaker
• Battery placement
• LED indicator
• Button mechanism
• Optional compass capsule
5. Smooth, ergonomic exterior (no sharp edges)

Preferred Skills:
• Industrial Design
• Product Design
• Mechanical CAD
• SolidWorks or Fusion 360
• Experience with small handheld electronics
• Understanding of enclosure design (plastic OR metal — both are fine)

Important Notes:
• The casing material is not decided yet (could be plastic or metal).
• The model must be designed so it can be produced later using plastic molding or metal machining.
• I will provide a simple pencil sketch + written description.
• NDA signature required before project starts.
