im having a bad time trying to slice it with slic3r, it just gets stuck on triangulated mesh.
3 things to try when you have an issue with slic3r that I've found
1) run through cloud.netfabb.com
2) Try adding more memory or slicing with a different machine (or try a different version of slic3r)
3) Use MeshLabs' quadradic decimation filter to cut the model's resolution in half.
Have you tried running it through Netfabb?
