I just got a new iPhone 8 Plus and love the design mentioned. I redesigned it to fit an iPhone 8 Plus size.
I have added a dove tail version for people with a small surface printer. Hope it works. You need then a resolution of 100%. You ll probably need to paper-sand the connection a little bit to make it fit. (Or try some soap before).
And ... a lion design (not easy to print), a bird design.
