Air duct for CTC 3D printer stepper drivers

Hi,

All the fans started to be too loud so decided to upgrade them. I draw air duct to ensure proper air flow over stepper drivers as air flow provided with new fan is lower that original fan had. Nothing special on printing, supports needed.

Print Settings

Printer:

CTC

Rafts:

No

Yes

Resolution:

0,1-0,2

50

Notes:

On Makerbot desktop, increase default value of Support to Model Spacing up to 0,8mm. This is to avoid support structure sticking to duct wall.
