Make sticker optional on the M2 wheel

@Piboso
Would like to have the sticker optional on the M2 wheel template. Made a white and red lined rim and it's impossible to line up the lines because the sticker is "one size for all sides" on the template. So if front is aligned the rear is off and so on (see image, click on it for full view).
