Also to note, if you are printing your armour, and need to scale it up, the Ab plate posses a problem.
The main and side button plates will also scale up, placing them out of proportion with reference material and ABS and Fibre glass R1 kits available.
I think the best options will be to speak with the file creators and ask if they can indeed make those details separate print files, so the size remains the same, and they are simply attached to the Ab plate.
The couple we have seen are noticeable, so this would be a good option to have.
