printrbot jr v2 cooling fan duct

By rp10007

 The duct end (barely) clears the build-platform adjustment nut when homing on my machine. If you're brave you could dive into the (really lousy) Openscad and make the duct a little lower and longer. But there's quite a bit of airflow even on the far side of the nozzle as it is. Also, the end of the heat-break duct may need trimming unless your printer is really good at overhangs.
