Numball Puzzle https://photos.app.goo.gl/HoU5AN6xry5eMsRG6 Meet the Numball, a 3D printed number puzzle ball that's sure to challenge and delight. Kudos to Devin Montes for the inspiration behind this project! The Numball is a fusion of a Rubik's Cube and a mechanical Simon Says memory game, making it easy to play and fun to solve. To get started, you'll need to gather the following non-printed parts: * 48 - 6x3mm Neodymium Magnets * 1 - 11mm Ball Bearing DESCRIPTION The Numball consists of eight identical pieces with unique numbers on each face. When assembled, one half of the ball features numbers 1-4 in a counter-clockwise direction, while the other half showcases numbers 5-8 in the same direction. The ball bearing should be placed in the center to facilitate rotation. The assembly process begins by aligning the 1 and 5 numbers on either side of the ball. Make sure to insert one magnet with the north pole facing up and the other with the south pole facing up, alternating this pattern for each side. HOW TO PLAY Numball is best enjoyed with two or more players. Here are three games you can play: GAME 1 - NUMEMBER With the ball assembled and in its correct position, Player 1 twists it a quarter turn in any direction along any split. Player 2 must then reverse that move back to the original position using only the same moves (corresponding 1-4 to one half and 5-8 to the other). Once achieved, Player 2 makes two moves, followed by three for Player 1, and so on. The first player unable to return to the original position after matching moves loses. GAME 2 - QUICKBALL Disassemble the Numball into its eight pieces and mix them up. Then, set a timer and see how quickly you can reassemble the ball to its original position (corresponding 1-4 to one half and 5-8 to the other). The fastest time recorded is an impressive 7 seconds! GAME 3 - NUMBER TWIST Challenge yourself to twist the Numball about five or six times without looking, then try to return it to its original position. Sounds easy, but be warned: this game requires some serious thought and spatial reasoning. PRINTING CONSIDERATIONS When printing each piece, consider using a medium setting at least to hold tolerances in the model. The recommended settings include 3 shell loops, no infill, 6 bottom/top layers, a layer height of .15mm, and an extrusion width of 4. ASSEMBLY INSTRUCTIONS To ensure a secure fit, apply a small amount of adhesive or epoxy to the magnet recesses. When placing magnets, make sure one is north-facing up and the other south-facing up on each side. This may seem tedious, but it's crucial for the Numball to work as intended. Happy printing!
