I printed several box cutter knifes but was not happy either with the shape or function. This is a new design of a fast and easy 3d printable box cutter knife for 18mm blades. It has a knife-like handle and fixes the blade at an arbitrary position with a screw.
To move the blade, turn the knob halfway, move the blade, and turn the knob back to fix the blade.
The screw is based on this script: https://www.thingiverse.com/thing:193647
- I added cutter_body_v2.stl and cutter_fixation_v2.stl. The difference between the original and this version is that the distance where the blade slides is increased from 18.2mm to 18.4mm
- An alternative version can be found under https://www.thingiverse.com/thing:3788426
The part are printed with a wall thickness of 1.2mm. The screw is printed with 100% infill.
