Looking for advice on enclosures

Hi all,

I've dabbled in the past in personal projects, but I'm making a gift for may daughter and would like some extra polish on the finish.

I've built a train departure display board using an ESP32S3 Nano and a 3.12" SSD1322 OLED screen and need a simple enclosure, ideally with areas pre-cut out for USBC power and the screen.

What is the best approach here? How do you guys handle this type of thing for your projects.

Thanks
