Sorry all! I meant to post a video of the moire/vernier effect in action, which is the most eye-catching part of the whole project, as the main image for the post, but it didn’t upload. And now when I try to edit in a link, or post a link to it in the comments, it’s telling me “blocked URL.” But there’s a link on the printables page, and the version with the older version is in the imgur gallery which is linked.
