PRECAUTION:
You can use it as a toy, if you just dont mount real blade. But if you want, you can screw on a real trapezoidal blade, but: BE REALLY CAREFUL! Trapezoidal utility blades are really sharp. If you do this- don't give the model to your kids. Knife haven't any redundant safety mechanisms, and it can expand spontaneously. Remember, that you are using them on your own responsibility.
Want a Custom Cover? 🎨 Limited-Time Offer!
If you print this model, I’d love to see your "Make"! Your feedback is incredibly important to me, especially since this model involves a complex mechanism that I want to ensure works properly across different printers.
💡 As a thank-you for your support, I’m offering something special:
I’ll create a custom lever or housing variant with your graphic(svg) or text of choice! This could be your logo, a personal message, or any design you’d like.
🕒 This offer is limited, so don’t miss out!
➡ Simply upload your "Make" and reach out with your design request. Let’s make your version truly unique!
You can also fork project, it's on GPLv3. Sources:

made in FreeCAD 1.0. If you aren't designer, you can just edit some dimensions, parameters.


Made in Poland

To mount you need:
- 1x10mm M2 screw(cheese, hex)
- 3x4mm M2 screws(cheese, slot)
- 4x4mm M2 nut
I recommend such orientations and supports for v1.2(tree supports for build plate only):

Project includes carrier with clip for relatively safe transport.
Always put it inside when not in use!!

If you have any problems- write to me before leaving a negative comment. I've come across a lot of model problems in process of drawing and testing them, that can be easily fixed. And if not: Project is easy customizable, and I can prepare parts with slightly changed dimensions/clearances especially for your request. More elastic spring for other materials? Larger clearances? no problem. Just PM Me.
I need feedback because I want the project to be able to work on any printer after it is made. Feel free to PM me.
