Shower Door Lock / Clip Fix (Custom Rail Catch)

Designed a simple and effective clip-style lock for a sliding shower door that keeps it securely closed by engaging into the rail.

This part solves a common issue where shower doors don’t stay shut properly due to worn-out or missing original retainers. The clip snaps into position and provides just enough resistance to hold the door closed without making it hard to open.

The model is compact, easy to print, and can be adapted to different rail sizes if needed.
