RoBo R1 E3D Sided Fan Duct

thingiverse

A remix of a remix! The common feedback with other remixes of this fan duct idea is that it directs too much air onto the hot end and causes some 'thermal runaway' errors and general heating problems. I have just added an aesthetical curve to each duct so air becomes directed either side of the hot end nozzle. This also means that both ducts don't just blow air into each other, in theory giving a better airflow cooling. Above the duct is a ~12mm flat surface, this has been added so that I could stick a strip of LED lighting to the duct to further light up the print when the printer is used with Octoprint.
