I would like to import data from an STL file of a 3D object to MATLAB and create a 2D contour plot of it. Does anyone have any ideas about this? Thanks!

I am trying to create a contour plot showing the thickness of this odd shaped 3D body similar to a topography map. If I had a matrix of x and y coordinates with the thickness at those locations (not just height but thickness) then I could create a contour plot. I do not know how to import the STL to MATLAB however and extract this information from it. Any tips would be greatly appreciated!

STL files have a very specific format you can exploit to gather your data automatically. Try using "textscan" followed by "strsplit" to get the x, y, z coordinates of the vertices.
