I actually have found that the Yamaha models are very well thought out. I've never come across any fitting issues, even with the MT 01 templates in several parts....Though their latest VMax had a few problems (I later heard that they updated the files to address these)

But it is possible for the scale to be 'off' if you printed the parts at different times (my printer used to do that) but you should be ok if you printed all in one go.
