120-cell internal structure

thingiverse

To reveal the internal framework of the 120-cell, I opted to start by projecting three interconnected rings of ten dodecahedrons into a 3D space using a perspective transformation. To circumvent the necessity for support structures, I divided it into two distinct parts. The advantage of this division is that the pieces can be assembled in numerous different ways. Printed at a scale of 400%, resulting in a height of approximately 10cm. UPDATE: If you print part two twice, it becomes possible to fit all the components together, as depicted in the final picture. Printer Settings Printer Model: Cubicon Single Rafts: Not Used Supports: Not Required Resolution: 0.15 mm Layer Height Infill Percentage: 15% Notes: The model was sliced with Simplify3d and printed using white ABS material. To assemble part two, place the top pentagon on the build plate (inverted). Design Process I designed this model by combining a 120-cell structure with Meshmixer. The files contain multiple shells, yet they do not overlap, thereby ensuring that they will not cause any issues for your slicer.
