Simple junk drawer used to separate my junk in one of my smaller drawers. It was designed to fit 3 in a drawer measuring 165mm wide X 519mm long x 76 mm high. I'm sure you can change the dimensions easily to fit your own needs.
I added 3 divider slots to separate the random things in the drawer. You can always increase the number of dividers to fit your needs.
It works well for me, I hope it does for you too!
