Ball Valve Visual Lock – 3D Printed (PETG)

This 3D-printed ball valve visual lock is designed as a clear, physical reminder that a ball valve should not be opened or closed in a home or educational setting.

It is ideal for situations where you want to:

Prevent accidental valve operation at home

Clearly signal “do not touch” during maintenance or experiments

Demonstrate lockout concepts for training or educational purposes

The design physically blocks the valve handle and allows the use of a standard padlock, making the valve state immediately obvious at a glance.
