About this 3D model

Remix of the PrintrBot Gear Head Mounting Block (https://www.youmagine.com/designs/printrbot-gear-head-extruder) The different versions vary in the gap between the two gears in 0.1mm increments. I'm using the 98 version - 9.8mm between the two gears, you may want to use one with a larger or smaller gap.
