Measurements inaccurate

I had around 4.3mm give in a keyboard project, 4.1mm seemed ideal.I was wrong, there was a huge blob of solder on the wiring connecting to the battery itself, pushing the thickness towards 5mm which is false advertising.It's now sat in a battery recycling unit at Lidl as Amazon don't offer drop off returns and I don't have a printer.
