Create a 3D-printed sundial that displays the time digitally!
We’d like to share this Julien Coyne invention with you. Sundials generally project a line or triangle to indicate the time. It is designed so that when light passes through it, it displays the shapes of the numbers. This device gives you access to the time in an original way. Simple and effective, it can be used anywhere in the northern hemisphere, at any time of day.
