Annular Cooling for Prusa using 80mm fan

This uses a 80mm fan (attached to one of the rods of the printer) attaches to the cooling duct with a vacuum hose. All parts where printed with PLA.Tabs are in place of the 2 small plates for holding in the belt.

I have yet to experience any heat problems; this may be due to the vortexing of air that, according to the simulation, happens between the fan duct, and the nozzle (the simulation did have a model of the nozzle, it is omitted in the picture) keeping the plastic cool.
