Rotary USB key holder

3D model description

Here is an improvement of my usb key holder.

It differs from the first by the installation of a ball bearing and a plate that allow it to rotate on itself. It is therefore easier to choose the key, simply by giving it a small impulse.

You will need a 608Z bearing.
