Scaling upward is no problem, unless you go insanely big. For scaling downward, the main issue is that the margins will shrink as well. The original has a margin of .5mm on either side of the bottle, which shrinks in proportion to the amount you scale it with. It depends on the accuracy of your printer, but I'd say a scale of .8, resulting in a margin of .4mm, will still be no problem.
