Sleeve for Raspberry Pi 3/2/B+ with camera and GPIO access

I really like this slim sleeve case, but needed access to the GPIO header for a project.

Two versions are available:
- Full header accessible
- Only pins 1-8 accessible (others covered)

See my other things for removable mounting clips and brackets that fit this case.
