Stencilia Font required(Put it in the same folder as the .scad file): https://www.dafont.com/stencilia.font

There is support for text and a SVG being cut out of the patch, both an SVG and text together takes a while to render but is pretty cool.

The part of the SVG that you want cutting out should be black, I've provided an example SVG.

There is also a seprate file that allows adding multiple SVGs, unsurprisingly this take even longer to render.
