This was generated in the Fusion 360 generative design workspace, I simulated a disk above another to generate an efficient topology between them. I added a top to the podium that curves around the branches. Here is my tutorial on how to use Fusion 360 Generative design: https://piledltd.co.uk/generative-design-shelf-bracket-tutorial/

This is my favourite generation from this collection: https://than.gs/m/970863 with a top I modelled to match the geometry of the generation

Tall versions shown were stretched in a slicer.
