■ OVERVIEW
Enhance workplace safety and domestic security with this compact Ball Valve Lockout device. Specially designed for standard 1/2" ball valves, this Lockout/Tagout (LOTO) solution physically prevents the valve handle from turning, ensuring secure maintenance operations. It is a highly practical, low-profile safety tool for workshops, plumbing systems, laboratories, or home automation setups.
■ KEY DESIGN FEATURES
. Interference-Based Blocking: The geometric shroud tightly embraces the valve body and blocks the handle's path, preventing accidental or unauthorized operation.
. Dual-Position Locking: The versatile geometry allows you to secure the valve in either the fully OPEN or fully CLOSED position, depending on your safety requirements.
. Built-in Zip-Tie Channel: Features a dedicated retention slot and a curved guide rail to securely anchor a standard 0.14" (3.6 mm) cable tie.
. 100% Support-Free: Fully optimized for additive manufacturing. The internal and external angles are engineered to print cleanly without the need for removable supports.
■ FILES INCLUDED
.STEP file: High-fidelity parametric CAD file, perfect for scaling to other valve sizes.
.STL file: Clean, high-poly mesh export ready for immediate slicing.
Project .3MF file: Pre-configured settings with optimal slicing parameters for enhanced strength.
