The stl files should be enough, but you can modify the Fusion360 files if need be. If you want other file formats, please let me know.
Print orientation is as stl file

I wanted to create an easy wall mount for my long board, without it making the wall dirty.
This made me make the 70mm design. I now got a new electric long board with 90mm tires. This made me make the 90mm version and made me play around with Fusion360 generative design.

About the generated design:
The generated design is made to be able to handle 150kN and for additive manufacturing.
The sides were not perfectly flat in the design. Therefor the stl was fixed in Blender.
If you try to generate design yourself, I would be keen to see them and hear what you have tweaked.
