Replacement thing - blower fan?

Somebody at work noticed my 3D printer and was immediately smitten. I couldn't blame the guy - who wouldn't fall for that kind of technology? He asked if I could create a real part using the thing, and I said "why not, bring me something to make and I'll do it for you." He ended up bringing me the broken blower fan looking part shown here and asked if I could replace it. It turned out the parts for the affected machine are no longer in production, and this part is the only thing needed to get it running again. I said I'd give it a shot, but you can see that the part was incomplete and he didn't have the broken off bits. I made some educated guesses about the missing portion of the part, and he seemed okay with them. Here's the result printed in silver PLA. I figured I'd also make him an ABS version after he does a test fit. The part feels incredibly solid and stiff - I printed it at 8 layers with 10% infill. I finally got to see it in action, and here's a video:
