Seagate 5TB Backup Plus Drive Rack

I currently use an array of several 5TB Seagate Backup Plus hard drives for my Plex server. These keep getting in my way and I knock them around, so this rack lets me get them off my main desk surface. I put some little rubber dot feet on the bottom so it doesn't slide around. There is a small border wall bump out on the top for an additional drive or another item (Raspberry Pi, etc.).

These are the drives: https://www.seagate.com/consumer/backup/backup-plus/

STL and SketchUp files included. Thanks!
