DW660 blower redirection

Little chute to redirect output air from DW660 to blow onto the cutting area.

Two little pegs are intended to fit within the output ports to hold it in place. Two holes near the top of the part are intended for #6 sheet metal screws to act as standoffs against the router body to adjust the orientation of the chute.

I used a zip tie to hold the chute in place against the router.

There is no "good" surface to put on the bed but I managed to print successfully with one of the facets near the bottom of the model laying flat on the bed.
