Parametric air assist nozzle with mounting tab for drag chain

Remixed from http://www.thingiverse.com/thing:25515
I intended to lost PLA cast this so I manually added supports that double as sprues,
Added:
a bracket and mounting holes for attaching cable drag chain
a second grub screw mount for stability and centering.
Modified:
I adjusted the inlet nozzles interface to the body I felt it was too close to the outlet.
