Customized S6 Case (You Add Lettering)

S6 Case with Custom Text.

--THIS IS A WORK IN PROGRESS

This is my first attempt at using customizer.Im trying to make this fully customizeable so that the letters are cut out of the plastic so when you print it, the stencil will be hollow on the case. Any feedback would be greatly appreciated. I do have the rasied text working so feel free to customize away with that. However remove lettering is still a work in progress.
