Hi! My name is Artur, and i am a UX/UI engineer.
I present to you one of the smallest knives that can be 3D printed. I designed this keychain knife for myself so that it's always in my pocket and doesn't take up much space. I spent over a year developing the blade locking mechanism and tried many variations before finding a safe one.
Features
Ultra-Compact: Less than 35mm long — disappears on your keychain.
Weight only 2 grams
Unique blade locking mechanism in two positions
Easy to print and only 1.12 grams of plastic
Print Settings
These are the settings used for the printed version shown in the images:
Material: PLA
Layer height: 0.20 mm
First layer height: 0.20 mm
Infill: 15%
Infill pattern: Grid
Supports: No
Assembly instructions
Take a 9mm utility knife blade and break off all the segments. We only need the segment with the hole.
Install the blade into the holder
Align the blade holder and the press body. Insert one side and press the other side.
I hope you like this knife keychain.
