I'm am pretty new to Rhino software (I've spent most of my time using Solidworks). My current university project has led me to try out Rhino as a more effective way of creating my product however I am stuck with how best to create the shape.

I've gone over many tutorials which has helped me gain a better understanding of what I need to do but I still can't seem to succeed.

I've attached the hand drawing of my product to be modelled below, if someone could outline the best workflow to follow or even any tips on how to achieve the (what I think are) complex curves?

Thanks in advance!
