About this 3D model

For the TL Aluminatus - the deck fan is a pretty hefty 24v 80mm blower, and it creates serious drafts when attempting to print ABS. It's also very, very loud. I did two things to minimize the impact on printing, and as an added benifit, reduced the overall sound volume. 1] turned fan 180 degrees to "blow" towards the bottom of the printer rather than up through the deck - so now it sucks rather than blows. 2] Designed this duct so that the air is pulled from the side, away from the print surface. As an aside, even with the duct fitted, you have enough clearence to fit Jeff's two part bed corners.
