I added thickness to the model so when you slice it you don't end up with only floating tubes.
I included the low poly model with no subsurf modifications and the medium and high poly model with the Catmull subsurf modifier applied. If you'd like to use a different modifier feel free to do so with the attached blender file using blender 2.8.
I finally got around to printing this for a friend and it printed great. I will have him post a make once he does the post processing work.
The source's original model comes from the model posted by OGLoc069: https://ogloc069.deviantart.com/art/Injustice-2-Sub-Zero-733074209
3/23/19 - Creased the back faces edges so the subsurf modifier wouldn't distort them. The edges are much cleaner now.
3/20/19 - Used the original back face and scaled it down to 0.925 then bridged the edges so the back side of it looks much better now.
- 3/19/19 - Deleted the back face and applied a solidify modifier to it to give it some thickness
