What
- Engineered a custom internal snap-fit for a circular sock storage system, giving a secure and repeatable connection.
- Developed a two-part assembly: a male plug with cantilever snaps and a female receptacle with an engagement gap.
How
- Optimised the internal wall gap to allow enough deflection during insertion while keeping a high retention force once locked.
- Designed the geometry for 3D printing, so the snap arms stay flexible and strong over many assembly cycles.
Results
- Achieved a tool-free, plug-and-play assembly that simplifies the product for users.
- Removed the need for screws or adhesive by building the fastening into the parts themselves.
