As a 3D product designer, I help hardware founders, jewelers and product teams get designs that are ready to print, cast or mold. I work in product design, injection mold DFM analysis, PCB enclosure design and 3D jewelry CAD, using SolidWorks, Fusion 360, Moldflow, Rhino and Matrix. My team and I check every file for fit and manufacturing problems, so you find them before you spend money on prints, wax or steel. You get clear updates, honest advice and on time delivery. Send me a message with your idea, sketch, board or CAD file and let’s get started.

FAQ
What do I need to send you to get started?
Send your 3D file in STEP, SolidWorks, IGES or STL. Tell me the plastic (ABS, PP, PC or Nylon), your expected quantity and your mold maker if you have one. No finished CAD yet? Message me first and we will find the best way to start. You will know exactly what to prepare.
How does the process work, step by step?
1. You send your file and plastic type. 2. I audit wall thickness, draft, undercuts and ribs. 3. I run Moldflow on fill, gate and warpage. 4. I fix your SolidWorks CAD and write a plain English report. 5. You review and ask questions. Clear at every step, no guessing.
My mold maker already reviews my design. Why do I need this?
Many mold makers review a design mainly to quote and cut it. I work for you. You get an independent check of every risk and fixed CAD to take back to them, so you negotiate from facts and avoid paying for steel changes later. A small check now protects your whole budget.
Which option is right for my project?
Every project is different, so just message me with your project details and files, and I'll give you a proper quote for your project.
What results can I realistically expect?
You get a clear list of problems, fixes applied to your CAD and simulation of fill and warpage risks. This lowers the chance of costly mold changes, though final results also depend on the mold maker and material. I design so you can move forward with confidence.
Is my design safe with you?
Yes, your files are used only for your order and are never shared or reused. I can sign an NDA if you ask. I reply fast, explain every change in plain English and deliver on time, so you always know where your project stands.
What if I need changes or my mold maker has feedback?
Send me the feedback and I will update the files to match. If a fix would change your design intent, I tell you first and show options, so nothing changes without your approval. You stay in control until the files are ready to cut.
