I think you maybe using an older version of openscad.
Please try the latest development snapshot

please see the complex radiuses and it would be difficult with pure openscad

Although I have written the same in openscad also, but it's not perfect.
Initially I was just copying the functions I have written in openscad , later on I realised the same code can be written much efficiently in numpy.
That's a learning curve.
For example, if you download the wheel_final.scad file, you can see the roundings of so many intersection lines.
For this to work file dependencies.scad also need to be downloaded and kept in the same folder

It was not very difficult for a person like me who doesn't have much background in softwares.
At the same time it's just one of the approach where points calculation is done with another software and then these points are passed on to openscad.
I have found that calculations are much easier in python as there are many supporting libraries.
Thanks

Wrote almost all the functions of openscad in jupyter notebook.
you can refer to the page below for few examples:

It is just to demonstrate that the points list can be passes from jupyter
notebook to openscad.
You can notice the fillet at the intersection between the hub and the post,
which is not trivial for openscad
