Spinning Nut!

🔩 Spin the Nut! — The Ultimate Physical Puzzle Fidget Toy for OCD

💡 Design Inspiration

You must have played "Screw Out Puzzle" or "Water Sort Puzzle" on your phone, right? The satisfaction of organizing chaotic colors into perfect order is practically a lifesaver for those with OCD! But how can a fingertip swipe on a screen compare to the mechanical touch of something truly held in your hands? That's why I've "physicalized" this puzzle game with 3D printing! It not only retains the irresistible color-sorting logic but also brings a stress-relieving twisting tactile experience that screens simply cannot replicate.

🎮 Game Rules (OCD Challenge Guide)

• Initial Level (Scramble): Before starting the game, completely scramble the different colored octagonal nuts (4 of each color per set) and screw them onto any of the surrounding bolts. Depending on the difficulty you want to challenge, leave 1-2 "empty bolts" in the center as transfer spaces.
• Winning Condition (Cure): By continuously moving and twisting the nuts, ultimately sort all nuts of the same color into their designated places, perfectly gathered on a single bolt.
• Core Rule (No Crossing Boundaries):
  1. Only the topmost nut on a bolt can be twisted at any time.
  2. Same Color Attraction Principle: The topmost position of the target bolt must be a nut of the same color before you can screw it in (empty bolts are an exception). No stacking of different colors is allowed!

🔥 Ultimate Hell Mode (For Severe Color OCD Sufferers)

Think the basic version is too easy? It also supports a "color-matched" gameplay mode:

• Rule Upgrade: The bolts themselves are printed in colors corresponding to the nuts. In the final sorting, not only must the nuts gather by color, but they must also be screwed onto bolts that perfectly match their own color! Each step requires precise global deduction; one wrong move can lead to an unwinnable situation, pushing the brain-teasing factor to the max!

🛠️ Product Highlights

• Smooth Damping for Stress Relief: The thread tolerance has been iteratively optimized for PLA Basic, providing an extremely comfortable micro-resistance feedback whether you're quickly spinning or delicately twisting. Both the sound and feel are incredibly therapeutic.
• Industrial Aesthetics for Your Desk: Choose high-quality PLA materials and your own color scheme.
• Modular and Freely Interchangeable: The base, bolts, and storage box fully incorporate a magnetic design, ensuring secure storage and allowing you to adjust and change the bolt layout at any time based on future level developments, keeping the experience fresh for a long time.

⚙️ Hardware List and Assembly Instructions

• Magnet Specifications: Use uniform 4×2mm strong magnets.
• Installation Method: The hole design does not require any glue; simply press the magnets firmly into the corresponding holes for a tight fit, avoiding the hassle of glue overflow. In some cases, magnets may come loose due to printer model or filament type; please reinforce with glue.
• Magnet Distribution (26 pieces needed for the full set):
  • Dedicated Storage Box (12 pieces total): Features a top-and-bottom lid design, with 6 magnets in the top lid and 6 in the bottom base, ensuring a tight seal for secure portability.
  • Game Body (14 pieces total): 1 magnet is embedded under each detachable bolt (7 total), and 7 magnets are embedded in the corresponding positions on the game base. This ensures a firm magnetic attachment while allowing for flexible rearrangement of the base layout.
