MK8 Drive Gear

This is a evolution of the MK7 Drive Gear. The smaller diameter gives 35% more power.

If you need a replacement gear, or you're designing your own custom project, this is the part! Very sharp teeth to dig into the plastic filament for the best grip ever. Direct drive of the filament will give better prints.

Our MK8 Drive Gear was Best In Test in the benchmark test from Airtripper.
