ruler holder

This is a practical 3D-printed ruler holder designed to keep measurements stable and precise during use. The device features a compact block shape that securely grips the ruler, while the built-in adjustable knob allows it to be tightened or loosened as needed. Made from bright red filament, it is highly visible and easy to locate among tools. The holder helps fix the ruler in place on surfaces, preventing slipping and improving accuracy when marking or measuring. Its simple yet effective design makes it a useful accessory for woodworking, crafting, or any task that requires consistent measurements.
