Y000 tri-point screwdriver (iPhone) (Bear Flat, Bath BA24)

I'm attempting to repair a phone for my daughter's school friend (and save it from disposal) but come up against Apple using unusual screws inside. Turns out I need a y000 tri-point screwdriver to remove a connector cover which I don't have to hand.

While I'm waiting for a set to arrive from China, If anyone's got a spare one (or even just to borrow for a few days) that would be appreciated - within cycling range of Bear Flat.
Can you help with this request?
