Dice ball

This is a unique 3D printable spherical dice that uses an internal steel ball and six cuplike recesses to create a truly random rolling behavior. Instead of traditional numbered faces, the dice “settles” into one of six stable internal positions, making it perfect for board games, party games, decision-making, or gift exchange games (e.g. dice-based present selection games).

The design features a smooth outer spherical shell with internal geometry that guides an 8mm steel ball into six distinct resting positions. When rolled, the ball moves freely inside and naturally settles into one of the six cavities, acting like a hidden internal face system.

Key Features:

• Six internal cuplike detents for consistent 6-result outcomes
• Hidden internal steel ball mechanism (no visible faces)
• Smooth spherical exterior for satisfying roll behavior
• Great for board games, party games, decision-making, or “gift exchange dice” style games
• Fun fidget-style kinetic movement and randomness

Recommended Setup:

• Standard version designed for 8mm steel ball (recommended size for optimal balance and dice-like proportions similar to a standard cube die)
• Scaled variants available for 10mm and 12mm steel balls (entire model scales proportionally)
• Optional 0.2mm nozzle optimized version included for improved detail and smoother internal cavity accuracy when printing for 8mm ball version

Remember to clean your print bed or use some glue.
