I broke one of my keys for my hp elitebook g3. found a few models ehre and there but the scissor distance wasn't correct.
needed a bit of knife poking to get the overhang alright.
Key is a bit taller than standard, maybe try sink it into the bed in your slicer a bit if it is too much for you.
works great after two months still.
