Instructions
- The only part that may need support is the handle. If you have problems with adhesion and overhangs I would suggest printing the "with supports" versions of the STL files.
- The following videos show how to assemble the knife.
- When assembling the knife it is important to note the orientation of the flexing slider. Its sides are slanted so it only works in a specific orientation which can be seen best in the animation.
- I would strongly suggest using a lubricant on the flexing slider. It will work without lubricant but its action is much smoother when lubricated.
- The threading on the screw is (M8x1.25) and the threading on the knob is (M5x0.8).
This image shows the recommended orientation to print each part.
