Description

We CNC mill these bolts in-house to our specifications.  The process we use produces parallel teeth that provide excellent drive traction on a variety of filament types, including flexible filaments.  They will not cause filament to twist or grind.  The teeth are directional to provide maximum grip in all of our extruders:

  • Itty Bitty Belted Extruder
  • Itty Bitty Double Extruder
  • Itty Bitty Double FLEX Extruder

The double extruders require two bolts.

If you’re using this bolt in one of our Itty Bitty extruders, we recommend starting with an E-Steps setting of 615 steps/mm.
