Based on perfectly fit model by Kirk Valko [1]. I fixed only one disadvantage - buttons. I was not able to press volume buttons. Therefore instead of holes I created a buttons - they are easy to find by touch and really useful for controlling your phone.
There is also second version called low-profile which reduces the big rim around the screen and makes it almost flat with screen. This suits me better because my thumb does not get stuck on the edge while swiping.
Printed with FLEX filament - TPU.
