>>10910482I wouldn't say it's the go-to method for the kind of thing you're looking to do, but it's an option. The machine is a multi-use cutting tool, so people are always discovering new uses with different materials.
And yes, the price tag is big. I bought my gen 2 silhouette second hand for $60, but it's still much more expensive than most tools like a dremel. However, some libraries nowadays do have them (and 3D printers if you didn't know) available to use for free! Same with paid makerspaces which would lower the cost. In general, it's a pretty popular tool, so there was a chance that you might've had one already, but didn't know to use it in this way.
Since you don't, I think your fix is the best!
