Earth crust layers model

My son had to create a model in school for science showing the layers of the planet earth showing the inner and outer core, the mantle and the crust. I created this model as 4 separate pieces in Tinkercad so that they all fit together and printed them in different colours. To top off the model i took a map and using the lithophane web site I then made the model as accurate as I could. The final model is 110mm wide.
