Hi, I am an Industrial Product Designer helping hardware startups and brands turn ideas into market-ready products.
I specialize in 3D CAD modeling, plastic injection molding, PCB enclosure design, and Design for Manufacturing (DFM). Using SolidWorks, Fusion 360, and KeyShot, I deliver manufacturing-ready files (STEP, IGES, STL) and realistic renders.
I focus on functional, buildable designs to avoid costly factory errors. Message me with your sketch or brief to bring your product to life!

FAQ
How do you guarantee the model won't fail or warp during 3D printing?
I design specifically for Additive Manufacturing (DFM). I optimize wall thicknesses, eliminate non-manifold geometry/unclosed shells, minimize unnecessary overhangs requiring supports, and account for material shrinkage (PLA, PETG, ABS).
Will the parts fit together if I am printing a multi-piece assembly?
Yes. I apply standard mechanical tolerances (typically 0.2mm to 0.3mm clearance gaps depending on your printer type—FDM vs SLA/Resin) to ensure press-fits, thread engagements, and snap-joints function smoothly without filing.
Can you convert a mesh file (STL/OBJ) back into an editable CAD model (STEP)?
Yes. I perform reverse engineering to rebuild low-poly, damaged, or uneditable STL mesh files into clean, parametric STEP or native SolidWorks/Fusion 360 models that you can actually modify and manufacture.
What if my factory or print shop requests a specific format or 2D spec sheet?
I provide universal CAD exchange formats (STEP, IGES, STL) as well as 2D engineering blueprints (PDF/DXF) with critical dimensions, tolerances, and thread callouts required for toolmakers or commercial print vendors.
My print bed size is limited. Can you split a large part into inter-locking pieces?
Yes, I can divide large CAD models into smaller interlocking sections with alignment pins, dovetails, or bolt channels so you can print them in pieces and assemble them seamlessly.
