They are made from the 20190612_equatorial.svg file in my github repo. You can't see the shadow of the gnomon on the clear one, but you can totally see it projected (correctly) on the ground! The etching on the white background didn't show up initially, so I set some ink onto. It's nothing fancy; I just smeared black whiteboard marker ink over the face of the dial, and then wiped off the excess ink with my hand. It's not waterproof...
