Welcome! Right now things like this aren't necessary. When I was your age after I had learned to meditate better I used to go to my astral temple. Basically creating an astral temple is the safest way to go when you are still young. You don't necessarily need props and tools because it's the intent that matters in your workings but if you feel you absolutely need them you can imagine them with intent in your temple exactly the things you want.
I would read about it here through this link
