I found a nice scan of a rubber duck made with an Artec Spider 3D scanner: https://viewshape.com/shapes/e5mifgysuba
I oriented and converted the color model with MeshMixer, it's the zip file.
I also edited the model with MeshMixer by cutting a flat plane (flat base) and sculpting it, that's the STL file.
The author marked this model as their own original creation. Imported from Thingiverse.
