Raspberry Pi NAS case

I'm running a Raspberry Pi 4 (4GB RAM) with OpenMediaVault 5 as a cheap NAS (with Plex-Server and Ubooquity-Server in Docker) with a couple of external HDDs. Over the time I added more harddrives and so I needed to to come up with a way to store/organize them. While I was at it, I added a holder for my Network switch as well.
To reduce noise from vibrations, I added some foam I had laying around under both feet.

Right now it's working quite well, but I'm thinking on adding something to hold the HDDs better in place, probably printed in TPU.

I had to print it in 2 parts because of it's size, but I had no issue glueing it together with superglue.
