print any shelves you need and fix them with the clip .
no supports
my printer is out of order so cant print them , but this is a picture of what you will get .

As the shelves are not designed for heavy things, I think large nail will be enough, or use transparent nano double side tape .https://amzn.to/3BWPKku
You can also use Sossai bracket like this one :
