Fan Shroud Successful?

[MSURunner]

http://www.thingiverse.com/thing:74789 was a fan shroud that I had created a long time ago that didn't do what I wanted (too much back pressure with my fans on hand and had the potential to run into the towers), but it keeps getting a lot of likes and downloads. Do I need to re-examine this design? Is it actually working well for those that have tried it? If so, I'll remove the giant warning I put on there to try to dissuade people from using it and publish some cleaner files/a 40mm off-shoot.

The reason I have liked using your fan shroud in the past is because it offers good flow, could be improved through removal of the squarish kink, and it prints fairly easily.

My one dislike about it is the bulk and weight of the fan.

Now all off these pros and cons work against each other of course because like life there is never a perfect no compromise solution.

Some slight weight reduction and smoothing of the channel would be great! But how to do it without making the part harder to print....

Gotcha, the kink was in there to prevent blowing air across the nozzle which can cause ALL sorts of issues in printing in PLA, but I could try something different on that. It seems most people that are wanting to print in PLA are mounting their hotend's top from the effector plate, not using a riser to mount the hotend. Is that the case? If so, then this could be redesign around that concept, similar to the other design I have for printing in PLA, which has a much better air flow.

I seem to be more confident about the hotend when it isn't on a riser. On the other hand it reduces my maximum height. Not that I run near that maximum yet, but I COULD and that would be horrible when it happens.
