My wife and I recently got a beautiful walnut dresser. We wanted to further divide the top shelves, so I made these custom-fit dividers out of PG Medium Walnut (perfect match!).

The design is like an uppercase I. There are two pieces that are pressed snugly against the front and back. With slots, these keep the column-divider pieces firmly in place without glue.

Here’s the Cuttle project if you want to make your own:

It’s parametric so you can input your own width, depth, and height and it will generate the cut files for you.
