5-Tier Adjustable Shelf Plastic Stacking Clasp

This is my first original part design, created out of necessity. It’s a replacement plastic link clasp that fits into the ends of modular shelving units, allowing them to stack securely and increase height. The model is based on the connector used in common 5-tier shelves (and likely compatible with similar brands). Simple but functional, perfect if you’ve lost one of these small yet essential pieces or broken one as I did.
