120-cell internal structure

To show the internal structure of the 120-cell I initially choose to use 3 touching rings of 10 dodecahedrons projected in 3d space using a perspective transformation.

To avoid the need for support structure I cut it into 2 parts.

The nice thing of this cut is that it can be put together in a lot of different ways!

Printed at 400% scale, which makes it about 10cm tall.

UPDATE: If you print part 2 twice you can fit them all together (as shown in the last picture).
