After numerous self-done measurements on each case type, this is what I've come up with. They are full-size editable PSD files, meant for those who prefer a snug and smooth fit without the cover shifting around. Please note that while the Vortex 5&6-disc case shares the same dimensions as the Viva Elite 7-10, the latter's panels are narrower, resulting in a wider spine. I've added additional guides to the Viva template, with that in mind. Enjoy!
P.S. - I will not be making any other sizes.
