Paper craft sundial

Here are instructions for a paper craft sundial I built last night.  The hard part was doing the trigonometry for getting the gnomon to be at the right angle after folding--I hadn't done much trigonometry for a while, especially in regard to laying out a three dimensional object (the gnomon is wider at bottom than at the top).  With the script complete, construction takes about fifteen minutes.

  1. Thanks so much for this. My daughter came home on Friday saying he needs a sundial by Monday. With no instructions on how to construct one or how accurate it has to be. I looked up the latitude and longitude for her school and we're [printing out this one so she can decorate it.
