As I've collected more records I've struggled with them leaning against each other while they are stored in my Ikea Expedit.
This is a simple divider which splits a cube into four even sections. It's easily attached to the underside of the shelf with some double sided tape.
The original model was designed to provide minimal contact with 12" records. The “XL” version extends a bit further for more support.
The model comes in two parts for smaller print beds. Should also fit the Ikea Kallax cubes.
The author marked this model as their own original creation.
