Sizing of OBJ

[RooSter 0]

Hi there,

I'm a total novice, but love my new Ultimaker 2+.

I have designed an object that is made up of 18 separate parts, and they need to be printed in direct and precise relationship to one another as they slot in and support each other. I designed in ZBrush, and exported as OBJ file, saving every part separately at a tool, once I'd sized them all together in a ZPR file in ZBrush.

Now, I can load each file separately in to Cura, but they appear different sizes, and the first time I printed multiple objects from the platform, this turned in to a spaghetti junction situation, so I'm going for printing off separate objects. I'm wondering what is the best way to get the individual OBJ files sized to the right output size? Do I have to size manually? This will be rather difficult as there are internal ball jointed sockets, which are the things I need to size...

Any help or advice will be graciously appreciated!
