Balanced D30 Dice | Opposite Faces Sum to 31

A custom-designed 30-sided die (D30) based on a Rhombic Triacontahedron, carefully numbered for a clean and balanced layout.

Features

✅ 30-sided dice (D30)
✅ Opposite faces always sum to 31
✅ Balanced number distribution
✅ Unique geometric design
✅ Optimized for 3D printing

This model was designed to create a visually balanced and satisfying number layout while avoiding direct number sequences whenever possible. Opposite faces are paired mathematically:

1 ↔ 30
2 ↔ 29
3 ↔ 28
…and so on.

Perfect for:

• Tabletop games & RPGs
• Math lovers & geometry fans
• Dice collectors
• Educational demonstrations
• Unique desk toys

Print Settings

• Supports: Minimal supports recommended
• Layer Height: 0.12 mm recommended for better detail and cleaner numbers
• Infill: 10–15% works well

I printed mine at 0.12 mm layer height because I personally prefer a smoother finish and sharper-looking numbers.

If you print one, feel free to share your result. Happy printing 🎲
