This is a case for my portable RetroPie console. It's for a Raspberry Pi 3B+ and a OSOYOO 5 inch DSI screen.
Feel free to modify the Fusion 360 Model for your needs.
A detailed description on the setup, the used software and history of the project in my blogpost: RetroPie Revision 2
Below is a list of hardware components used in this project. The links go to AliExpress, but you may also find them at Amazon, eBay or your preferred hardware dealer.
You want to print with a brim to avoid any warping at the corners. I printed the base using "Octagram Spiral" as the bottom layer pattern to make it a little more interesting to look at.
Be sure to flip the lid by 180 degrees before printing. No supports needed.
