**CAD Designer for Mechanical MDF Toys | CO₂ Laser Cutting | 3D Puzzle & Moving Mechanisms** Ended

We are developing a new range of **premium mechanical MDF wooden toys, 3D puzzles and DIY model kits**, inspired by products similar in concept to Robotime/ROKR-style mechanical models.

We are looking for an experienced **CAD/Product Designer** who can design products specifically for **CO₂ laser cutting from MDF/plywood sheets**.

This is not just a graphic/vector tracing project. We need someone who understands how to design a complete physical product that can be **laser cut, assembled without difficulty, and function mechanically**.

### What We Want to Develop

Products may include:

* Mechanical vehicles
* Cars, bikes, trains and construction models
* Gear-driven toys
* Moving mechanical models
* Automata
* Mechanical animals
* Marble-run style models
* DIY wooden engineering kits
* Educational STEM models
* Decorative kinetic models
* Complex 3D wooden puzzles

The designs should consist primarily of **interlocking laser-cut MDF/plywood components**.

### Your Responsibilities

You will be responsible for:

* Developing the complete concept and mechanical structure
* Creating accurate CAD drawings for every component
* Designing parts specifically for **CO₂ laser cutting**
* Designing proper slot-and-tab/interlocking systems
* Calculating appropriate tolerances and **laser kerf compensation**
* Designing gears, shafts, linkages, cams and other mechanical movements where required
* Optimizing parts to reduce MDF sheet wastage
* Creating properly nested laser-cutting layouts
* Ensuring the product can be assembled practically
* Creating exploded views or assembly sequences
* Making modifications after prototype testing
* Preparing final production-ready files for manufacturing

### Required Deliverables

Depending on the project, we would require:

* DXF
* DWG
* SVG
* AI / CDR if applicable
* STEP / STP
* 3D CAD source files
* Laser cutting layouts
* Individual component drawings
* Exploded assembly drawings
* Bill of Materials / parts list
* Assembly sequence or instruction references

All designs must be **editable and suitable for commercial manufacturing**.

### Important Technical Knowledge

You should preferably have experience with:

**CO₂ Laser Cutting**

* MDF / plywood laser cutting
* Kerf compensation
* Press-fit and friction-fit joints
* Slot tolerances
* Material thickness variations
* Minimum cutting distances
* Sheet nesting / material optimization

**Mechanical Design**

* Gear systems
* Mechanical linkages
* Cams
* Cranks
* Springs / rubber-band mechanisms
* Moving assemblies
* Mechanical tolerances

### Preferred Software

Experience with one or more of the following is preferred:

* SolidWorks
* Fusion 360
* AutoCAD
* Autodesk Inventor
* Rhino
* CorelDRAW
* Adobe Illustrator
* Onshape
* Similar professional CAD software

### Who We're Looking For

We are particularly interested in designers who have previously worked on:

* Laser-cut wooden models
* Mechanical wooden toys
* 3D wooden puzzles
* ROKR / Robotime-type products
* Wooden automata
* DIY model kits
* STEM toys
* Flat-pack products
* CNC/laser manufactured products read less
