Say goodbye to disposable utility knives! This 3D-printed wallpaper cutter features a modular, split-design construction: the outer shell can be repeatedly printed and replaced, and it works seamlessly with standard 18mm utility blades. Whether you’re opening packages, trimming paper edges, or tackling everyday DIY projects, this tool is incredibly practical. Plus, with dual-color printing, you can create custom color schemes—making it an essential little gadget for desktop DIY enthusiasts!

🔧 Design Highlights

• Universal Compatibility: Designed to fit the most common 18mm utility blades on the market, ensuring low-cost consumables; when the blade dulls, simply swap it out instead of buying a whole new knife.

• Self-Locking Mechanism: Equipped with a knob-style locking slider that securely holds the blade in place once extended, preventing accidental retraction for safer use—and allowing easy adjustment of the blade length as needed.

• Comfortable Grip: The shell’s thickness and curvature have been optimized for fatigue-free, long-term use, while customizable texture options enhance grip and reduce slippage during printing.
