Xteink X4 sliding cover w/ Strap and lanyard

Slim case remixed from Findtherror to add space for a elastic strap, a NFC tag, and holes for a tiny lanyard.

The file has not my initials ;)
I added
1 - lanyard holes
2 - access to USB port and pushing point
3 - slot for an NFC tag - you can use it as a business card
4 - holes and space for an elastic strap

I have made space for adhesive lining. You have to glue the strap in its slot before adding the lining.
