About this gig
Need a professional 3D CAD prototype for your product or mechanical idea? I can turn your concept, sketch, reference, or existing design into a prototype ready CAD model.
I specialize in 3D CAD prototype design, product development, functional prototypes, and manufacturing.
I can create accurate CAD models based on your needs.
My services include:
- 3D CAD prototype modeling
- Functional product and mechanism design
- Product development and improvements
- Mechanical parts and assembly modeling
- Prototype design for 3D printing and CNC
- Technical drawings and dimensions
- Design modifications and optimization
- STEP, STL, IGES and other CAD formats
- Manufacturing ready CAD preparation
I focus on practical designs with proper dimensions, fit, clearances, and assembly considerations. Your CAD can be prepared for prototype production, testing, revisions, or manufacturing.
Send your sketch, measurements, reference images, existing CAD files, or requirements. I will review the information and develop the prototype to your needs.
I can refine prototypes, improve functionality, and prepare parts for testing or production as needed.!
Delivery style preference
