Would be awesome if that is possible 
Regarding formed sticker thickness (which seems to be an issue for some, if I read this right):
I found that Blender provides a (moderately) simple and reliable way to offset any 3D formed surface perfectly rectangular (you can also set it to exactly 0.25 LDU). It requires a bit back-and-forth in converting your files though, but there's barely any knowledge required and it's free.
