Hello hello!

So I have been looking into getting a custom terrarium for a minute now but all of them are way out of my price range. I found a 36x18x18 front opening I think would be perfect for my BP to love and grow in but it the top is a screen top.

Anyone kniw now where I could get a solid top for it? Or any ideas on how I can make it solid?
Thanks in advance for your help!
