About this 3D model
This is a modification of Greg Frost's x-carriage with dual fan mounts and belt clamps for GT2 belts. The source file is a direct modification (ripoff?) of http://www.thingiverse.com/thing:9869 to include the extra features mentioned in the description. To work with this source, you will need the full source from thing:9869 which includes configuration.scad. Just to be clear, this isn't my design or SCAD code. I modified another users files to fit my use. Since it is usefull to me, it might be to others.
