Here's a thing from Thingiverse: http://www.thingiverse.com/thing:735038 It was created using the Customizer app at: http://www.thingiverse.com/apps/customizer/run?thing_id=735038 Here are the instructions to customize this design: To customize, choose these options: Adjust the fan's angle (naz_mani) to 0 degrees. Set the second fan to a speed of 60 RPM. Choose the first fan to run at 40 RPM. Increase the pipe's number to 1 unit. Tighten the angle between components to 0.501 units. Enlarge the wall thickness to 2.5 units. Select all movable parts (a_mani) as stationary objects. Increase the total number of faceted surfaces ($fn) to 90 points. Specify the angle for the conical shape to be 90 degrees. Adjust fan two's depth to 40 units. Choose fan one to operate at a reduced depth of 20 units. Design the manifolds and ducts to extend just over zero units in length. Keep the sizes of the second fan (ds_fan2) and first fan (ds_fan1) at exactly 3.4 units each
