As a HS science teacher I love getting kids outside. This star clock, while obviously not the most accurate measure of time is a really neat teaching tool. Not only do you have to find Polaris and the big dipper, but also learn a little something about the history of telling time. This is a neat little device. Here's a link to help. https://skyandtelescope.org/observing/make-a-star-clock/ Printed this version in PETG which offered a little more flexibility when pushing the pin through the two disks.
