Sipeed Longan Nano case

There are a few cases for Sipeed Longan Nano on Thingiverse, But it's a case for a development board, I want to change the case to fit things that I add, I'm guessing you do.

So the files include the OpenSCAD source file.
You want something slightly different - go for it.
You think you can improve it - go for it.

Straight off the printer it just clicks together, no clean up, no supports needed.
