I used MeshMixer to make this 123D Catch scan 3D printable. I deleted all the surroundings that were also scanned (kitchen counter etc.), made a plane cut of the solid to create a flat base and oriented it upright. I touched up the model a bit with the ShrinkSmooth brush and scaled the model up to 125 mm in height.
