3D printed Hilbert curve using two types of ink

This Hilbert curve approximation serves more as a test "to produce objects with overhanging parts that are currently very difficult, or impossible, for them to print" using two types of ink (PVA and PLA). After dissolving the former, the latter remains.

Next up, a Menger sponge?
