As I mentioned in one of the comments, the original .obj file was very difficult to print. There were 4 surfaces that were not "unioned" together and so my slicer was having trouble rendering them. (Simplify3d).The basic problem is that it is very difficult to figure where exactly two parts overlap. Often the slicer ends up "exclusive oring" the two shapes, and where there are 2 shapes overlapping, you end up with nothing, which means the two parts do not really join.

So the files are:
lizard_highpoly_X.stl the 4 shapes separated
lizard_lowpoly_X.stl the 4 shapes separated

In order to make these I had to convert the .obj to an STL:
loaded the .obj file into simpify3d and then did a File->export Models->Export Binary STL

Then I wrote some fairly complicated code to split out the overlapping shapes and write out the new STL files and the new .scad files. (I will share this later if I can figure out how to package it up) UPDATE: I have it packaged up, but I can't post an exe file to thingiverse. or a .py file.

To use the 4 STL files in simplify3d:
1) load all 4 stl files into simplify3d.
2) for each one double click on it and press the button "Reset Position" (they should move to their proper place in the final model)
3) now work on them as a group if you want to move or rotate them.
4) print them as a group
5) NOTE: if you try to export the set of 4 models as 1 stl it will not work. I still have no way to combine the stl files together into 1 file, but at least I can print them!

and then some openscad stuff

lizard_highpoly_X.scad files that you can include in openscad to work with the shape (note it is very large so is slow)

lizard_lowpoly_X.scad files that you can include in openscad to work with the shape

lizard_highpolyV1.scad an example of how to include the highpoly shape0 (the tongue)

lizard_lowpolyV1.scad an example of how to include the lowpoly shape1 (one of the eyes) since this is a smaller file it is much easier to work with.

So download lizard_lowpoly_1.scad, and lizard_lowpolyV1.scad and put them in the same directory. Then in openscad load the lizard_lowpolyV1.scad file and work with it.

Notes:

You need supports. The belly and the tongue need supports to print. The legs have a fairly narrow attachment to the body which can make removing the supports very difficult without breaking the legs. The way I chose to print it was: I scaled it up to be bigger (I think 130%) I printed the bottom 25mm with 5 outlines and 60%infill and then the top using a more standard 3 outlines and 20%infill. and finally I moved the model down (z direction) by 0.2mm so that the feet would actually be flat on the build plate.
