This gear FDM made out of Nylon - tough and flexible plastic

No lubrication required
Runs quieter and smoother than Zamak
Only Nylons should be used for gears where a slippery surface is desired.
  All other materials (PLA, ABC, PET, etc.) will grind creating a plastic dust and eventually fail!
For details, please review all pictures and compare to OEM gear shown

Do not waste your money for ABS, PLA plastic gear that may strip or melt

Thank you.
