Hilbert bought a few pieces of strange furniture too many! Now he needs your help fitting them in his living room. A puzzle based on the fourth iteration of the Hilbert curve, consisting of 13 unique tiles. It measures approx. 13 cm x 13 cm and tiles are 3 mm high. The printed model shown is made of wood-infused PLA that has been sanded and painted with a wood stain to give it a distressed/vintage look.
