About this gig
Functional 3D Printable Parts & Mechanical Prototypes
Need a 3D-printable part or functional mechanical prototype designed from your idea, sketch, reference or existing component?
I can create accurate CAD models optimized for 3D printing, assembly and functional testing.
I can design:
- Functional mechanical parts
- 3D-printable components
- Product prototypes
- Enclosures and housings
- Brackets and mounts
- Mechanical mechanisms
- Multi-part prototypes
- Custom replacement parts
- Prototype assemblies
What you can receive:
- 3D CAD model
- Print-ready STL
- STEP / IGES files
- Multi-part assembly
- Assembly clearances
- Design modifications
- Engineering drawings where required
- BOM for multi-part prototypes
I consider wall thickness, clearances, fit, assembly, print orientation and practical manufacturability while developing the design.
The service is suitable for functional prototypes, proof-of-concept models, custom mechanical parts and small mechanical assemblies.
Software
SolidWorks | CATIA V5 | AutoCAD
Send your concept, dimensions or reference before ordering so I can confirm the design requirements and printing scope.
Delivery style preference
Please inform the freelancer of any preferences or concerns regarding the use of AI tools in the completion and/or delivery of your order.
