Thickness in Maya

Hi everybody. I'm trying to prep a model for 3d printing and I am attempting to give everything uniform wall thickness. My model is relatively complicated and when I select all faces and use the extrude tool my model ends up looking ridiculous. Is there any way to give everything in my file a simple wall thickness, or am I using the extrude tool to accomplish this in the incorrect way? I am looking for a strategy to take any model and give every surface 3mm thickness for example without changing the model visually. Thanks.

After you applied the extrude (with 'save history' enabled), did you go into the extrude node (using channel box or AE) and set the "Thickness" property to a small negative number?
If animation couldn't change the world, it wouldn't be such a Micky-Mouse place.

You might try using localTranslateZ on the extrude in stead of thickness. The thickness method uses a complex algorithm to attempt to preserve exact thickness and it is prone to problems on complex meshes. The localTranslate just extrudes the specified distance along the vertex normal, which can result in slightly varying thickness in curved regions, but is relatively free of artifacts.
