This is a really fun project that makes for a really satisfying desk toy. I'm certanly not the first to make a bismuth magnet levitator, but this is my spin on the concept. There are several things you'll need to buy to make this which are shown in one of the pictures.
Printing is very simple. Nothing too special. Although one thing I did differently is that I had the top and bottom layer patterns be Archimedean Chords.
