Description

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.

Print details

Material: PETG

Infill: 50% (recommended for strength and durability)

Orientation: As shown in photos

Supports: 1 point is supported by a tree support, as seen in image

PETG was chosen for its improved toughness and temperature resistance compared to PLA, making it suitable for practical, everyday environments.

Disclaimer / Safety Notice

This 3D-printed device is provided for educational purposes and home-use demonstration only.

It is not a certified safety device, not LOTO-compliant, and not intended for industrial, professional, or regulated environments.

The purpose of this model is to visually indicate and discourage operation of a ball valve in a home or non-critical setting.

It must not be relied upon to provide actual lockout, isolation, or protection against hazardous energy.

Always use approved, certified Lockout/Tagout equipment and follow applicable safety procedures and regulations where required.

How big pipe will this fit?

The designer has replied

@3dmaker101

sorry for the later reaction I missed your message. in open position 40mm max in close position 90+ mm and the handle should be about 22 mm max. I don't know where your from but I took the liberty to convert it for you. locked in Open Position (40 mm): 1.57 inches locked in Closed Position (90 mm): 3.54 inches Max Handle Diameter/Width (22 mm): 0.87 inches. hope this helps. good luck

Does this allow for it to be locked in both positions? I want to use it with the valve in the closed position.

The designer has replied

@3dmaker101

Yes absolutely both closed and open
