3D model description

This is my gravity utility knife design. I also made a toy blade if you just want to use it as a fidget toy. If you enjoy the design a like or make would be appreciated.

Thanks to FormFutura for providing the High Gloss PLA ColorMorph filament used in this post. I especially like the red and black color morph. You can get some for yourself by clicking my affiliate link

Instructions
- I recommend printing in a resolution between 0.2mm and 0.1mm.
- The only part that needs supports is the handle.
- The video liked here shows 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.
- 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).
- If the threading is too tight try printing the screw and knob individually or scaling them down in the x and y direction.

Hardware
- x2 4mm M3 screws, specs linked here
- x2 M3 nuts, specs linked here
- x1 utility blade
