Do not waste your money on ABS or PLA plastic gear that may strip or even melt!

These fine Nylon gears have improved design for better durability and performance
 compare to OEM and superior to other replacements

US made out of Nylon - tough and flexible plastic
Nylon naturally slippery, no lubrication required!
Runs quieter and smoother 

Only Nylons should be used for gears where a slippery surface is desired.
  All other materials (PLA, ABS, PET, etc.) will grind creating a plastic dust and eventually fail!
