au Xperia Z4 SOV31 (Inner) Case

thingiverse

I purchased au's SOV31 and it came with a phone case that had a weak adhesive that would fall off easily. To solve this problem, I replaced the strong double-sided tape that held it in place with a removable case. It should also work for DoCoMo's SO-03G. The left side of the guard is almost non-existent since it was made to be used primarily as a phone case. However, there's no reason why it couldn't be used as a standalone case. If there's demand, I might create a version with a guard on the left side too. I prioritized button ease of use and made the holes quite large.
