3D Designer

3D Designer – STL & 3D Printing Company Description H K EXPORTS is a manufacturer and exporter of handmade beaded fashion accessories and decorative products, combining Indian craftsmanship with contemporary international design. We develop original product designs for global clients, with a strong focus on quality, precision, and practical manufacturing. Role Description H K EXPORTS is looking for a 3D Designer specializing in STL file creation and 3D-printing-ready models. This is a part-time, remote position focused specifically on converting product concepts, sketches, reference images, and design ideas into accurate 3D printable models and production-ready STL files. The designer will be responsible for creating detailed 3D models that can be directly used for 3D printing, prototype development, and mould/die making. The role requires a strong understanding of 3D geometry, dimensions, wall thickness, tolerances, printability, and practical manufacturing requirements. Key Responsibilities * Create accurate 3D models from reference images, sketches, and product concepts. * Develop STL files specifically optimized for 3D printing. * Ensure models are watertight, manifold, and free from non-printable geometry. * Design practical geometry suitable for different 3D-printing processes. * Maintain appropriate wall thickness, clearances, tolerances, and structural strength. * Create models with clean surfaces and accurate dimensions. * Modify and refine existing 3D models according to manufacturing requirements. * Design models that can be used for prototypes, moulds, dies, and production development. * Identify and eliminate issues such as non-manifold edges, intersecting geometry, unnecessary undercuts, floating surfaces, and mesh errors. * Provide final files in STL format, along with other 3D formats when required. * Make revisions based on physical 3D-printing test results and manufacturing feedback. * Maintain organized project files and version control. Required Qualifications * Strong skills in 3D modeling and CAD/3D design. * Proven experience creating STL files for 3D printing. * Strong understanding of 3D-printing requirements and limitations. * Experience with software such as Blender, Fusion 360, SolidWorks, Rhino, ZBrush, 3ds Max, or similar 3D modeling software. * Ability to accurately model objects from 2D images, sketches, measurements, and reference photographs. * Good understanding of mesh topology, watertight geometry, wall thickness, tolerances, and print orientation. * Ability to create both organic/decorative shapes and precise technical geometry. * Experience preparing models for FDM, resin/SLA, or other 3D-printing technologies is preferred. * Experience designing models for moulds, dies, casting, or manufacturing will be an advantage. * Strong attention to detail and dimensional accuracy. * Ability to work independently and deliver files within agreed timelines. Important Requirement This position is not focused on rendering, animation, lighting, or marketing visualization. The primary requirement is: Reference Design → Accurate 3D Model → 3D-Printing-Ready STL File The selected designer must be able to create practical, technically correct, and production-ready STL files, rather than only visually attractive 3D renders. Work Type Part-time | Remote | Project-based Candidates should be able to share examples of previous STL/3D-printing work, particularly products or models that were actually 3D printed.
