Meet the Oxygen Knob, a compact, 3D-printed upgrade designed to replace the bulky oxygen wrench on bottle tops. Its bright blue finish adds a recognizable touch, while a smooth, slightly matte surface gives you a comfortable grip during routine adjustments. Designed for everyday handling, this knob slips into pockets, pouches, or lanyards without adding bulk.
Durability is at the core of its design. The knob is engineered to withstand busy days, frequent handling, and the rigors of a fast-paced environment. Its sturdy build means it can travel with you from patient rooms to storage areas without losing its shape or grip.
Flexibility in how you carry it is a key benefit. A built in key chain attachment lets you clip it for easy access, and the knob integrates with badge reels for hands free transport during long shifts. It is a small but practical addition to your daily toolkit.
