Box Cutter for Right and Left Hands

Box Cutter (Left & Right Handed Versions)

Tired of struggling with packaging tape or keeping track of your metal utility knives? This fully 3D-printable, fully plastic box cutter is designed to make opening packages quick, easy, and comfortable.

Designed with a secure grip in mind, it features a finger ring and an ergonomic curved profile to prevent slipping while you work. The serrated edge is optimized for easily slicing through packing tape and light cardboard.

• Print-in-Place: No extra hardware, screws, or metal blades required. It prints entirely as one solid piece.
• Ergonomic Grip: The finger hole design gives you excellent leverage and control while keeping your hand secure.
• Serrated Edge: Quickly grips and tears through standard packaging tape and box seals.

Recommended Print Settings

• Material: PETG is highly recommended for durability and edge retention, though PLA will work for lighter duties.
• Wall Loops/Perimeters: 4 to 5 walls. (More walls will make the cutting edge much stronger).
• Infill: 35% - 55% (Gyroid) for maximum rigidity.
• Layer Height: 0.16mm or 0.20mm works great.

Usage Note Since this is a 100% plastic tool, the edge is designed for tape, paper, and light cardboard. Over time, the plastic edge may dull with heavy use, but you can always quickly print another one!
