This is an updated version of my previous case.
The v0 had several issues when 3D printed:
* the pattern on the lid wasn't thick enough, which made filling impossible. I simplified the pattern with fewer cells, and made the lines thicker.
* the hole for the Micro USB port was too low. I moved it a millimer higher, and made the hole larger for better tolerance.
Here's a picture of the v0 printed:
