Hi guys, Finally got my 4th replacement rMBP, and aside from a little yellow tinting to the bottom (I'll live), the bottom panel seems to be very loose and moves a fair bit. Is there a specific name for the type of tool used to open the rMBP? I'd assume its available cheaply on eBay or whatever, but it would help so that I buy the right one and get this thing tightened up. Also, would making the screws too tight cause creaking noises from the chassis? As my previous 2 had that issue, but the bottom panel seemed to be almost glued down due to there being no give at all. Thanks in advance!
