T-Display-S3 Case Shell (with separate buttons)

I recommend this back cover: https://www.thingiverse.com/thing:5664019

!! One side of the buttons is taller than the other, the taller side should be the side sticking out through the button holes for best fitment !!

I have improved the button mechanism by making the buttons separate from the shell, this mainly just allows you to use a different material/color for the buttons but also can help for those who cant get the seams to print correctly on the original (i couldn't).

Also made the reset button hole smaller, corrected its position, and made it square instead circular with an inside chamfer to hopefully reduce the chance of the button getting stuck when removing it from the shell.
