Default [Tipo]Missing and broken power button

Hi guys, as the title says the membrane that holds the power button in the housing has broken and I lost the power button itself, and now I have to wake the phone with a key because my nails aren't long.

Do you guys know any ebay link or something to buy a housing () or a homemade method to make it easier to wake up?

Every link sells front and back housing, but i only want the back housing.
