This is a replacement slider and knob designed for 18-mm blade craft knives. It is intended for replacement when the original thread is worn out, the screw cannot be tightened, or the knob itself is damaged.

I've made two sliders: one for the Olfa utility knife, and the other for the NT Cutter utility knife. Please print the slider that matches your knife brand. The knob part is universal for both. Please print the parts to replace the damaged parts on your knife.

What is needed besides the printable parts:

• 1 M4 nut

  

• 1 M4 hexagonal bolt

  

Note:

• The bolts embedded in the knob need to be fixed with glue.
• Although printing with PLA material is not a problem, I suggest using ABS filament, as its material is the same as the original.
