About me
I’m a 3D designer focused on turning ideas into practical, well-built digital models. I work on custom 3D printable products, mechanical CAD, collectible toys, product prototypes, and manufacturing-focused designs. My work includes STL, 3MF and STEP files, CAD assemblies, technical drawings, BOMs, and exploded views. I also design products with FDM printing, injection molding, TPR, and silicone manufacturing in mind. I enjoy taking a rough idea or reference and developing it into a clean, usable 3D model.

3D Product & Mechanical CAD Design
Jul 2026 - Jul 2026 • 0 mos
Developed detailed 3D CAD models for functional products and physical product concepts, focusing on accurate component design, practical assemblies, and manufacturing requirements. My work includes building individual parts, creating complete assemblies, defining connections and clearances, and organizing products into structured CAD files for prototyping and production development. I also prepare STEP files, exploded assembly views, BOMs, and technical drawings with relevant dimensions and tolerances. Projects often involve moving parts, adjustable components, detachable elements, and multiple-piece constructions where fit and assembly need to be considered from the beginning.
3D Toy & Collectible Product Design
May 2026 - May 2026 • 0 mos
Created custom 3D product models for toys and collectible products with manufacturing in mind. My work included developing character-based forms, refining surfaces and proportions, modeling separate components and accessories, and preparing the geometry for injection molding and production considerations. I also worked on a TPR soft-toy concept with integrated facial details, rounded surfaces and molded-product constraints, focusing on clean geometry suitable for further tooling and manufacturing development. These projects strengthened my experience with collectible toy design, product modeling, TPR, silicone and plastic manufacturing requirements.
