Como Triacont. Puzzle #1

cults3d

A three-piece puzzle assembles into a rhombic triacontahedron, a polyhedron with 30 identical rhombic faces. The basic piece resembles a spoon and would hold liquid perfectly. Three spoons can be assembled into the rhombic triacontahedron, but it's missing some essential parts. The other two pieces are modified spoon pieces that have these parts added to them. This results in a three-piece coordinate motion puzzle where all pieces move differently. The rhombic triacontahedron has a dihedral angle of 144 degrees, which poses a significant challenge for 3D printing due to its overhangs. However, as 3D printers continue to improve, they're becoming better at handling these overhangs. I use supports on all pieces because the faces come out very clean when printed with them. Piece two contains an internal overhang that was initially overlooked during setup. By placing support only on the build plate, it still turned out fine. Although it seems like the pieces don't fit together well, this puzzle actually holds together quite tightly. This is thanks to its coordinate motion design, which requires all three pieces to move simultaneously for it to come apart. If the pieces are one color, it makes the puzzle even more challenging to disassemble. This unique design serves as an interesting starting point for other creations. I've modified this design so that all three pieces are identical, but they're extremely fragile and hard to print accurately. Additionally, I have two more designs in progress, pending figuring out how to print the pieces successfully.
