Similar to the Acoustic Wall Partition, Hexa-Hush is a hollow form filled with cotton batting for sound absorption. My research proved cotton to be the best infill. For maximum sound absorption, six to eight cotton batting cutouts are recommended.
3M strips (affiliate link) can be used to attach the Hexa-Hush to the wall. Here is a link to the cotton batting I used in the Hexa-Hushes.
The video below shows how I put the Hexa-Hush together. One of the Hushes in the video is covered with mirror paper (affiliate link) that I bought from Amazon. It cuts easily with a craft knife.

I included two half bottom choices in the model files as the model without the extra wall prints faster.
