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.
