This week's selection is Norwegian designer Even Erichsen's Shopping Bag Handle.
The design is incredibly simple, yet totally useful for almost anyone. These days most people struggle with heavygrocery bags filled with calories. The Shopping Bag handle simply fits under the lift strap and saves your fingers from unwanted indentations.
This is a model that should be relatively easy to print on almost any personal 3D printer, it is also available at no charge on CGTrader.
