For the door pocket I have these two items:
Small case that I’ve had a few of many for years. Mostly for things like laptop power bricks/cords, but also used in multiple cars for small items. This one currently on Amazon is purple, mine happens to be red. But Amazon will have other similar items.

Then in the front of the door pocket, I have this for small garage. It’s silicone, so no rattling, etc.
