I will do custom product design, concept to cad and prototype 3d model
Ryan
About this gig
Do you have a brilliant idea for a custom product but don't know how to bring it to life? Are you trying to secure investors or run a Kickstarter, but you need a physical prototype and high-end visuals?
I specialize in Product Prototype Design and Concept to CAD modeling. Every great product starts with a rough sketch or reference photos. I bridge the gap between your imagination and reality. I will take your raw product concept, engineer it into a functional 3D CAD model, and provide the exact files you need for 3D printing and rapid prototyping.
Services included:
- Concept to CAD transformation
- Custom product design & 3D CAD modeling
- Files optimized for 3D printing (STL) & CNC (STEP)
- Photorealistic 3D renders for pitch decks & marketing
- Working from reference images and rough sketches
Why choose me:
- Strict NDA signing to protect your invention
- Beautiful 3D renders that attract investors
- Engineering-focused (your prototype will actually work)
Lets turn your idea into a real product! Message me today to discuss your vision.

A brilliant idea is useless if it cannot be manufactured.
I am a Senior Product Design Engineer specializing in turning rough concepts into factory-ready 3D CAD models. I don't just draw pretty pictures; I engineer products for mass production. Whether you need a 3D-printable prototype, a complex snap-fit plastic enclosure engineered for injection molding (DFM), or strict 2D technical manufacturing drawings, I deliver flawless files (STEP/STL/PDF).
From the initial concept to the factory floor, I ensure your product is structurally sound and ready for production.

FAQ
I only have a rough sketch on a napkin. Can you work from this?
Yes! That is my "Concept to CAD" specialty. As long as you can explain how the product works and provide some rough overall dimensions, I can turn your hand-drawn sketch or reference photos into a professional 3D CAD model.
Will you sign an NDA (Non-Disclosure Agreement) for my invention?
Absolutely. I work with startups and inventors daily, and I completely understand the need to protect your patent-pending product concept. Send me your NDA and I will sign it before we discuss any details.
Will the 3D model be ready for 3D printing?
Yes! I will optimize the CAD model for rapid prototyping and export a high-resolution STL file. You can send this file directly to a 3D printing service to get a physical plastic prototype of your custom product.
What are "3D Renders" and why do I need them?
3D renders are photorealistic digital pictures of your product before it is even manufactured. If you are trying to get funding, launch a Kickstarter, or show a presentation to your team, these high-end 3D renders make your custom product look incredibly professional.
What if I want to make changes to the design after seeing the first 3D model?
Product design is a collaborative process! All of my packages include revisions. Once I show you the initial 3D block-out, we can adjust the curves, dimensions, and features until it perfectly matches your vision.
Do you do the actual physical manufacturing?
I do the digital CAD engineering, product design, and 3D rendering. I provide you with the digital files (STEP/STL) which you can easily email to any local 3D print shop or overseas manufacturer to create the physical item.
