Como Triacontahedron Puzzle #1

thingiverse

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. Three spoons can be assembled into the rhombic triacontahedron, but it would be missing some parts. Two additional pieces are spoon pieces with these parts added to them. The result is a three-piece coordinate motion puzzle where all pieces are different. The rhombic triacontahedron has a dihedral angle of 144 degrees. This poses a challenge for 3D printing as it means that pieces always have significant overhangs, requiring support. However, 3D printers are constantly improving and handling such overhangs more effectively. One part was printed with no support, resulting in an acceptable outcome. Supports were used on the other pieces to achieve clean faces even when used. Piece two contains a considerable internal overhang that wasn't noticed during setup. Support was placed only on the build plate, yielding a successful print. Your mileage may vary. Although it seems like the pieces don't interlock well, this puzzle holds together quite effectively due to its coordinate motion design. All three pieces must move for it to come apart, making it more challenging when the pieces are one color. This puzzle serves as an interesting starting point for other designs. The original design has been modified to make all three pieces identical, resulting in very fragile and difficult-to-print components. Two additional designs are being considered but require figuring out how to print the pieces.
