What
- Engineered a modular attachment system for clipping interchangeable charms onto backpacks, footwear and keyrings.
- Developed a two-part assembly of a string-tethered anchor and a quick-release housing, so charms can be swapped without knots or tools.
How
- Applied a cantilever snap-fit that gives a tactile click on engagement and stays locked under tension during daily use.
- Set precise tolerances for a press-and-rotate release, preventing accidental detachment while staying easy to use.
Results
- Delivered a versatile hardware solution that turns static accessories into a swappable, collectable platform.
- Produced a design suited to high-strength printing or injection moulding, with rounded edges that do not snag fabric or skin.
Tools and processes: Snap-fit design, tolerance analysis, 3D printing, injection moulding
