Description
Clicking on a letter will take you to the page for that design.
This model is a safety version of the version using the existing utility blade.
Previous models use extremely sharp metal blades that rotate, requiring extreme caution when using. However, this model uses a relatively safe 3D printing blade, making it safe for even those unfamiliar with knives.
It's particularly suitable for use next to the printer, using Knife Mode to open filament bins or Scraper Mode to scrape the build plate.
Or, simply slide the slider and watch the blade move, making it a cool fidget.
Most of the assembly and usage methods are identical to those of models using existing utility blades.
The difference is...
Aside from the above, it has the exact same dimensions and details, and optimized tolerances ensure smooth operation.

You can also use a safer blade.
2. Combine the blade assembly and slider.
3. Position the blade assembly and safety lever A on the main body A as shown in the photo.
4. Position body B precisely on top of the assembly above.
5. Insert the slide button (from top to bottom based on the photo below).
6. Attach the cover for fixing the main body. (Insert while pressing the fixing spring part.)
7. Insert safety lever B in the direction shown in the photo.
For scraper mode, move both safety levers down (right in the photo) and then push the slider all the way up.
When using the scraper mode, push the safety lever B back toward the blade to support the blade.
I hope you enjoy this model. As always, your feedback is welcome.
