Space filling curves

These are three approximations of space-filling curves—continuous curves in two dimensions that fill an entire square region. There are three examples here: the Peano curve, the Hilbert curve, and the Moore curve. As shown in the final photo, with walls 1 mm thick and 6 mm tall, the final shapes are somewhat flexible. I'm also including a tray to hold the printed object.

When I printed these curves, I set the first-layer speed to a very low value to ensure the print adhered to the surface.
