About this 3D model
Just a very simple fan bracket for the Printrbot Makers Edition 2014. Keeps the extruder and it's motor cool :) two 3x20mm screws are neccessary to replace the 3x16mm ones on the Y-axis assembly. This thing was made with Tinkercad. Edit it online https://www.tinkercad.com/things/3ofHtX0WVFz
