Replicator 1 Cooling Fan

This is a work in progress, but has been printed and tested. This is a basic cooling fan attachment for a Replicator 1 with dual extrusion. It attaches under the extruder heatsinks and fans, replacing the fan spacers. It is designed to support a 40mm 24v cooling fan, similar to the stock replicator fans and blow air onto the extruding filament.

With the latest version, I've been getting very successful PLA prints.
