HARD SURFACE 3D Print Design Challenge
Design a Monopoly-style token that will be 3D printed.
Your token must be:
- Hard-surface modeled
- Geometric in design
- Clean and simple
- Structurally strong
- Printable without advanced techniques
This is a Beginner CAD Modeling Challenge — not a sculpting project.
STEP 01: THE DESIGN PROCESS

USE CANVA to create this. You login using your School Email. Link is below
YOU ARE NOW READY TO MOVE ONTO STEP 2 BELOW:
STEP 02: ORTHOGRAPHIC QUIZZES
COMPLETE THE QUIZZES AND UNDERSTANDING OF THE ORTHOGRAPHIC VIEWS IN D2L/ GOOGLE CLASSROOM.
Once you have submitted the quizzes – you now need to sketch your pencil sharpener in STEP 04!
STEP 03: DESIGN YOUR GAME PIECE
FORM a group of no less than 2 and no more than 5.
The lesson below, sets up the groundwork to start our project, going over the importance of researching, analyzing and bringing-in influences prior to designing our conceptual vehicle that delivers groceries door to door.
ASK YOUSELF:
- What theme does your token represent?
- What geometric symbol fits your theme?
- How will it remain stable?
- Where is the centre of gravity?
Submit:
- 2–3 thumbnail sketches
- One chosen final design
- Measurements
THINK ABOUT:
Does it need supports? (Try to avoid this)
Where could this break?
Are any parts too thin?
Are there overhangs greater than 45°?
🚫 STRICT DESIGN LIMITATIONS
To keep this project achievable and printable, you MUST follow these rules:
🔷 1. Hard Surface Modeling ONLY
Your token:
✔️ Must be geometric
✔️ Must use basic shapes (cube, cylinder, sphere, cone)
✔️ Must use bevel, extrude, loop cut, inset
✔️ Must have clean edges
❌ NO sculpting tools
❌ NO organic forms (animals, people, faces, food, blobs, curves that flow naturally)
❌ NO cloth simulation
❌ NO metaballs
❌ NO subdivision surface smoothing
Think:
- Chess piece
- Robot
- Trophy
- Building
- Tool
- Vehicle (simple block style)
- Crown (block style)
- Controller (low poly style)
NOT:
- Dog
- Person
- Hamburger
- Flame
- Tree
- Cloud
- Skull
- Wavy abstract sculpture
🔷 2. Shape & Structure Limitations
Your design must:
- Be ONE solid object (no separate floating parts)
- Be manifold (watertight)
- Have a flat base
- Stand upright without support
- Be stable and balanced
No:
- Thin spikes
- Tiny fragile details
- Hanging parts
- Long skinny arms
- Unsupported overhangs
🔷 3. Geometry Rules
To keep this beginner-friendly:
- Use fewer than 50 main modeling actions
- No modifiers except:
- Bevel
- Solidify (if needed)
- No Boolean operations unless teacher approved
- No imported models
- No downloaded assets
You must build it yourself from scratch.
🔷 4. Size Restrictions (For Printing)
- Maximum height: 1 inch tall
- Must fit inside a 2 X 2 inch square base
- Minimum wall thickness: 2mm
- Minimum connection thickness: 3mm
- Base thickness: minimum 4mm
If it is too thin — it will break.
If it is too tall — it will tip.
ROUGH DESIGN SKETCHES
INSTRUCTIONS: Everyone in your group should take a blank paper and start to make rough sketches. These sketches will be used for STEP 5 when you make orthographic views before you start your model.
SUBMIT FOR THIS STEP:
- All design styled drawings and any research.
- A final drawing of the product in isometric view.
STEP 04: PRACTICE DRAWING
Drawing Objects in Orthographic Views is a form of conveying analysis and design ideas, it is a fundamental skill set or a language of communication that most designers, architects and engineers use in their own professional practice- never too early to learn such a skill set.
In this step, you will draw a pencil sharpener.
SUBMIT: An image of a pencil sharpener with your orthographic drawing. See example Above. Tutorials are below by Mr. Balian
STEP 05: FINAL ORTHO DESIGN SKETCHES
INSTRUCTIONS: Using the pencil sharpener as a reminder of how to do this, take your ISOMETRIC DRAWING from STEP 3 to create your ORTHOGRPHIC drawings.
MY EXAMPLE:
STEP 06: BUILD YOUR FINAL PRODUCT IN BLENDER
Submit your STL and OBJ file
