Precision 9mm Snap-Off Utility Knife (Elegoo Edition)
Completing the utility knife family, this is the sleek, compact version designed specifically for standard 9mm snap-off blades. Perfect for precision craft work, opening packages, or cleaning up your 3D prints, this slim knife fits in your pocket like a pen while still offering the rugged reliability of its bigger brothers.
Matching the aesthetic of the previous models, it features the iconic ELEGOO branding designed for an effortless two-color print!
🌟 Key Features:
- Precision & Compact: Slim, pen-like profile makes it incredibly easy to handle for detailed and delicate cutting tasks.
- Smooth Sliding Mechanism: Features a thumb slider with a friction-lock design to easily extend, retract, and hold the 9mm blade in position.
- Built-in Blade Snapper: Just like the heavy-duty 18mm version, the back end of the handle features a specially designed slot. Insert the dull end of the blade and safely snap it off to instantly get a fresh, razor-sharp edge.
- Elegoo Branding: The embedded "ELEGOO" logo pops beautifully with a simple layer color change in your slicer.
- Pegboard Ready: Includes the signature built-in hook hole at the base, making it easy to store alongside your other printed tools.
🔩 Required Hardware:
- 1x Standard 9mm snap-off utility blade.
- 100% 3D printed! No metal screws, nuts, or springs required.
🖨️ Printing Instructions:
- Material: PETG or Tough PLA is highly recommended. The slider mechanism relies on a bit of flexibility to function smoothly, and PETG provides the perfect durability.
- Multicolor Text: To get the highlighted logo effect without an AMS/MMU, add a "Pause at height" (color change) command in your slicer right before the top layers of the text start printing.
- Infill: 30% (Grid or Honeycomb) is plenty for this slim design.
- Walls/Perimeters: Use at least 3-4 wall loops for strength, especially around the blade channel and the slider mechanism.
Complete your custom Elegoo toolset! Print it out, snap off a fresh blade, and let me know how it works for your precision projects!
