Kallax Drawer Insert Spacer

The Kallax Insert Space prevents the drawers from being pushed too far into the shelf.I was tired of my Kallax drawers not being flush with the front of the shelf. My Kallax shelf doesn't sit with its back right up against the wall and every time I closed them, they would push back past the back edge of the shelf until they stopped at the wall. This left a huge annoying gap. These fit on the bottom or top edge of the back wall of the drawer insert and prevent the drawers from pushing any further back. They are sized for the distance my shelf stands from the wall but I have included the Fusion 360 file in which you can modify those distances.
