The folks at Popbox now proceed to print the data that I sent them. You need not worry about the markings of where the screws go as they do all that.
The Mirai on the left of this sheet in Summer uniform will be the sloped side of the wheel meaning that a small slice needs to be cut off.
I didn't know this but if I did then I would have designed the wheel in a way so that the slice that gets chopped off does not affect the illustration - will show you what I mean further down the post.
The other side of the wheel (the side with the gears) is completely flat so no slices need to be cut off.
