Wanhao D5/D5S/D5 mini extruder gear

thingiverse

I recently experienced issues with my Wanhao D5s's stock extruder gear on the stepper motor. The gear was not long enough, frequently slipping inside the larger gear as a result. To resolve this problem, I created a custom model for the gear several years ago and it performed flawlessly for two years before shattering once again.\r\nAs my modeling skills have improved since then, I designed an even better replacement. I am now sharing my new design in case others may be experiencing similar difficulties with their own printers.
