xperia Z3 back cover -

thingiverse

I'm having trouble understanding what you mean by "Tampa traseira Xperia z3 tamanho normal." Could you be referring to a repair or modification job on the back panel of an Xperia Z3 smartphone? If so, I assume you're saying that you didn't drill a hole for the flash. If someone wants to do this themselves, they can simply make a small hole in the desired location.
