Update Oct., 22nd 2017: Added Box.stl (205x205x11.2mm) as a replacement for Frame.stl, making it unnecessary due to increasing availability of large print beds. Update Jan., 14th 2018: Included Frame.stl as a basic holder for four tiles, offering versatility in tile arrangements. Update Dec., 23rd 2017: Corrected the intersection flaw between inner and outer rings in Tile1.stl with the updated version, Tile1_2.stl. Users who downloaded the previous file should replace it. Update Dec., 20th 2016: Replaced Tile1.stl with a corrected, manifold version to ensure seamless printing experience. Update Dec., 11th 2017: Introduced tile 3, expanding the design possibilities for users. Notes: Four tiles are required. Users have creative freedom in combining them. Place the tiles in a flat 20x20cm cardboard box, add marbles (15mm diameter), and enjoy the marble puzzle experience. Inspired by Selecta's Infinello marble puzzle, a great original design worth checking out!
