Don't know why I didn't mention that earlier.

If you'd like to explore that option, there are countless vids on YT on DIY chameleon enclosures.
Here's a 4-part 'How to' that I liked on building one from window screen kits available at home improvement stores.
There's an old carpentry & quilting adage... "Measure twice—cut once."
IME doing DIY projects, I would extend this to any project design—don't just jump in and start cutting. Do your research (look at a godzillion different enclosures and take notes of the features you like), think carefully about what you want and how you're going to achieve it, and draw up an actual plan.
Drawing up a plan often exposes flaws and/or situations that weren't obvious during the thinking stages, and can cost a lot in BS&T if/when found during the build. It can save a LOT in the long run.
DIY enclosures
can save some money, but IME they're also just as likely not to save you anything,
BUT, you can get
exactly what you want, learn a lot during the experience, and get that little boost of pride & satisfaction at the end. Win-win-win!
