The Challenge
What will your learner investigate?
Can you design a personalised keyring. and explain the choices that make your solution effective?
Learning outcomes
- Create a three-dimensional design that meets a defined purpose.
- Use scale, dimensions and spatial reasoning accurately.
- Evaluate and refine the model for printability, function or appearance.
Connected learning
Design & Technology: CAD and prototyping; Mathematics: geometry, scale and measurement; Art: form and aesthetics; Computing: digital modelling.

What you'll need
Here's what may be useful for completing this activity. Requirements may vary depending on the learner, activity format and equipment available.
Materials & consumables
- Filament or approved 3D-print material
- keyring split rings
- design sketches.
Equipment, tools & software
- Computer
- beginner computer-aided design (CAD) software for drawing 3D models
- 3D printer
- callipers (a tool for measuring small dimensions accurately)
- suitable adult-operated print-removal tool.
Safety & preparation
- Adult operates the hot printer and removes supports
- check ring-hole strength, sharp edges and small-part risks.
These preparation notes support planning and do not replace a project-specific risk assessment or appropriate adult supervision.
