This model uses the mathematics of tessellation to link up with itself. Just rotate the model 180 degrees and see how it fits back together!

They are small and adaptable! My Ender 5 S1 can make 12 in just 3 hours at a normal speed!

This model can also be printed with magnets. Currently sized to fit a 1/16 in thick magnet with a 3/8 in diameter.
