120-cell internal structure

thingiverse

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). Print Settings Printer: Cubicon Single Rafts: No Supports: No Resolution: 0.15 mm layer height Infill: 15% infill Notes: Sliced with Simplify3d and printed in white ABS. Print part 2 with the top pentagon on the build plate (turn it upside down). How I Designed This Designed with 120 cell and combined with Meshmixer. The files do contain multiple shells, but they do not overlap, so they should not give your slicer any problems.
