About this 3D model

This is a palette-shaped tool for measuring how much spaghetti makes a serving (or two or three or four). It might work for other small pastas, but I'm not sure. (There were some other things posted that did this, but I had trouble getting Slic3r to handle any of them.) Serving size measurements are from the plans here: http://www.freepastatoolsplans.com/Assembly_4.htm
