Ormerod Hot End / Print Cooling Duct

thingiverse

Fits Ormerod 1, should fit Ormerod 2, no idea on compatibility with quick set nozzles as I don't have them. It probably won't clear the Duet enclosure on a standard size Ormerod 1 unless you shift that to the end of the Y axis. I liked the cooling performance of Kim Brown's Big Blue 360 but I wanted a PWM controlled fan for cooling. I took the BB360 and stripped it down, then added ducting for 2 separate fans. As with BB360, heater block needs rotating and you'll need to rotate your heat sink 90 degrees and drill a new mounting hole (which requires removing one of the fins, see pictures). Should print without support but you might have to do some cleanup if your printer can't do bridges very well :) Kim Brown suggested a backwash eliminator is probably a good idea since the heat sink fan is just above the bed. I recommend dc42's design: http://www.thingiverse.com/thing:441099
