Suggest software & Tutorial for learning to design 3D printable objects.

[Mustahsin10]

I want to design 3D printable objects (mostly casings for my electronics project). I have no idea about 3D printing / 3D printable objects. I want to learn as a beginner to become an expert. There are a bunch of 3D designing software available and a vast number of tutorials available on YouTube. Among them suggest a free, easy to use / easy to learn software and suggest associated tutorial. (YouTube channel / playlist links will be very helpful).  

I know it will take time to learn. So give me tutorial links which have detailed explanations.

Also I use a HP pavilion laptop (core i7 7500U, 8GB 2133MHz ram,  2GB NVIDIA 940MX with internal 2GB Intel HD 620 GPU).  so suggest software which it can handle.

Autodesk Fusion 360 (free version) is a good option https://www.autodesk.com/products/fusion-360/personal

Tutorials is a bit matter of taste and need, but here is a good starting point
