After multiple times of picking up the Swatch Carousel, having it fall apart, and having to re-sort all of the swatches, I created this simple add-on so that it doesn't fall apart to save frustration.

This bracket (printed 4 times) is connected together using 4x M3 Screws.

You can use any length between M3 x 8mm and M3 x 12mm as it is a through hole that is 10mm when connected.
