I will create injection mold, plastic parts, enclosure cad, solidworks rapid prototype
Ethan
About this gig
Mechanical design engineer with 7+ years of hands-on industry experience building hardware from initial sketch to factory floor. I deliver mold maker ready product design and rapid prototyping files for any plastic product needing clean 3d cad geometry. My focus is engineering components that pass prototype testing and move into mass tooling without friction.
Services I Offer:
- Enclosure modeling and plastic component mechanical layout
- DFM optimization for injection tooling and additive manufacturing
- Wall thickness balancing, structural ribbing, snap-fit design
- Conversion of hand sketches into fully parametric 3D CAD
- File preparation for SLA, SLS, and FDM rapid prototyping
Tools I Use:
- SolidWorks, Rhino 3D, Fusion 360, KeyShot
- File Formats Delivered: STEP, IGES, SLDPRT, STL, OBJ, PDF
Why Work With Me?
- Unlimited Revisions
- Direct alignment with mold maker tooling constraints
- Precise fit tolerances for multi-part mechanical assemblies
Please message me to discuss your project requirements before placing a direct order.
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.

Mechanical design engineer with 7+ years specializing in plastic product development, tooling architecture, production manufacturing. Core skills: • Injection Mold Design • Plastic Part DFM • SolidWorks CAD • Moldflow Analysis • Rapid Prototyping • Tooling Toolpath Prep. I use SolidWorks, Autodesk Moldflow, Fusion 360 daily to build production-ready molds with precise draft angles, wall thickness uniformity, gating layout. Drop a message to review your drawings or concept models before ordering.
FAQ
What materials or sketches do I need to send to start the product design?
You can share hand-drawn sketches, reference photos, dimensional constraints, or existing CAD components. I turn your visual ideas into structured 3D CAD geometry ready for prototyping.
How do you ensure the 3D CAD design transitions smoothly from prototype to final mold maker tooling?
I apply strict plastic DFM rules right from the start, including draft angles, uniform wall thicknesses, and internal ribbing, ensuring your 3D printed prototype translates directly into hard tooling.
What software platforms do you use for mechanical design?
I complete all solid parametric modeling in SolidWorks, use Rhino 3D for surface modeling when necessary, and generate presentation visuals in KeyShot.
Can you model internal mechanical features like snap fits, screw bosses, and living hinges?
I model mounting bosses, self-tapping screw threads, snap latches, and living hinges engineered within the stress limits of your chosen plastic resin.
Will the exported files be ready for rapid prototyping services right away?
Yes. I supply watertight, high-density STL files and 3D STEP files formatted for SLA, SLS, or FDM 3D printing labs and CNC prototype shops.
Can you provide visual renders of the plastic product before prototype production?
Yes. Standard and Premium packages can include clean, color-matched 3D visual renderings so you can review cosmetics prior to ordering physical prototypes.
