Shopping bag handle with storage compartment

This is an improvement of the Shopping bag handle that I remixed from the Backpack handle. Thank guppyk for the amazing design idea! 

I essentially rebuild the model, made the entire thing larger and increase the volume of the cavity. Two ideas are behind these changes:

1. With this increased volume, it is possible to store some light-weight shopping bags inside. Essentially the handle becomes also a casing for your shopping bag. As an example, I was able to fold and stuff the plastic bag that I got. I hope that we could save more plastic bag from being wasted.
2. The increase size of the handle is also better for gripping. now it should fill up more or less your entire hand. 

Feel free to scale up or down to if your hand are bigger/smaller.
