Rostock Cyclone cooling ring

This is a cyclone designed cooling option for a delta/rostock printer. I had designed this because space on delta printers is very limited and also so is weight.

I have trialed this method and it works brilliantly, I suggest join the 3 x 4mm o/d pipework inlets on the cooling ring to a 'Tee' and then use 6-8mm pipework up to a squirrel cage blower. Using an ordinary fan will not work this design requires pressure and volume, bit like an automotive turbo!
