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 robust 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.
