About this 3D model

Designed for the Duplicator 4, may work on the replicator 1 dual and other maker-bot printers. I modified the design by aubenc,I have used the same mounting idea as Aubenc but have made the design use 2 fans rather than 1 and added the provision to have the fans fixed in place by some m3 bolts. I have included the model as a solid-works 2013 part, for anyone who wishes to make there own modifications.
