Duct for 40mm Fan for Greg's X-Carriage

Description
My larger prints were lifting from the platform because the fan from the stepstruder was blowing cool air off the metal frame and onto the build platform, cooling the PLA more than needed. This vent forces the exhaust upwards and minimizes that effect. At 5mm it's the same thickness as the existing chrome grill and a replacement for it. The .stl and .sldprt has a blank face but I added a P for style pointz.
Instructions
These were just the settings I used. I haven't tried with others because it worked the first time (luckily)
In MakerWare:
Medium slicer with support enabled
20% infill, 2 shells
.25mm layer thickness
default temps and speeds
placed in the back right corner (warmest part of the build plate)

I think your fan is back-the-front it is supposed to be blowing into the heatsink. The other fan - the blower is what cools the PLA on the build plate. You can turn it off during the print by clicking the left button in the menu and scrolling down.

Quite possible! Though it was installed blowing out and I can understand drawing air through the heat sink first, flipping it around may be an even simpler solution than mine! As for turning off the fan manually, I do that almost every time. It's a bummer that it's not an option with Miracle Grue. If I wasn't able to babysit it and wait for the moment to turn off the fan I would slice it with Skeinforge instead.

I was able to print this without supports and it also seemed to be a little bit stronger at 100% infill.
Excellent. I was cautious about no support because I've had prints with less draft fail. As far as strength I felt that a minimal amount was necessary, and that the PLA wasn't mine to spend, but my company's. Has it had any affect on how the piece fits?
