The SeeMeCNC Hobbed Gear filament drive roller for the EZR Struder is better than ever!  We manufacture these steel drive rollers to precise dimensions in-house using our own teeth forming techniques.  In January of 2018, we slightly improved our design of the formed teeth for even better filament driving. The hobbed drive gear fit stepper motors with 5mm shafts and feature a set screw to securely lock onto stepper motor shafts.
