I design snap fit housings, plastic shells, electronic enclosures, bosses, ribs, and draft ready plastic products in CAD, with practical design considerations for injection molding, prototyping, and manufacturing.
Do you have a sketch, PCB, dimensions, reference image, existing model, or product concept? I can make into a plastic housing designed around your requirements.
What I Can Design
- Snap fit plastic housings
- Electronic enclosures and device cases
- Plastic product shells
- Bosses and mounting features
- Snap hooks, clips and retention features
- Internal ribs and supports
- Draft angles for molding
- Wall thickness optimization
- Covers, lids and mating parts
- PCB and component housings
- Multi part plastic assemblies
- Injection molding ready product geometry
- Design modifications and DFM improvements
What You'll Receive
- Editable 3D CAD models
- Snapfit features
- Functional bosses, ribs and mounting points
- Draft ready geometry
- Clean mating and assembly features
- STEP, STL, IGES and native CAD files etc.
I focus on fit, functionality, manufacturability, assembly, and clean CAD construction

I design 3D CAD for mechanical products, functional mechanisms and manufacturing.
My work spans kinematic joints, linkages and motion driven mechanisms, reverse engineering of worn parts, castings and scan meshes, plastic housings, snap fits and bosses, plus CNC fixtures, jigs and machining ready components.
I take concepts, existing parts or engineering requirements and turn them into editable CAD models ready for prototyping or production.
Deliverables can include STEP, STL, IGES, DWG, DXF, PDF drawings and native CAD files as needed.

FAQ
Can you design a plastic housing from a sketch or concept?
Yes. I can develop your sketch, dimensions, reference images, PCB, or product concept into a detailed CAD housing.
Can you design snap fit features?
Yes. I can design snap hooks, clips, tabs, retention features, and mating components based on your assembly requirements.
Can you add bosses and internal ribs?
Yes. I can design mounting bosses, screw posts, ribs, supports, and other internal features required for the product.
Can you prepare the housing for injection molding?
Yes. I can incorporate draft angles, appropriate wall thickness, ribs, bosses, fillets, and other DFM considerations.
Can you design an enclosure around my PCB?
Yes. You can provide your PCB dimensions, 3D board file, component locations, or other references so I can design the housing around them
Can you design both the housing and the matching cover?
Yes. I can create multi part housings with properly matched covers, snap-fits, mounting features, and assembly interfaces.
What files do you provide?
Depending on your project, I can provide STEP, STL, IGES, native CAD files, and technical drawings when required.
