+
+### Challenge Rules
+
+#### Materials & Constraints
+
+- **Filament**: 3D Fuel "Clearly Natural" - Available in two variations:
+  - PCTG (Polyethylene Terephthalate Glycol)
+  - PLA (Polylactic Acid)
+- **Maximum Filament Usage**: 250g per entry
+- **Model Specification**: Cylinder - 25mm diameter × 50mm height
+- **Print Mode**: Vase mode (approximately 6 grams of filament)
+
+#### Competition Categories
+
+- **PCTG Division**: For prints using Clearly Natural PCTG
+- **PLA Division**: For prints using Clearly Natural PLA
+- **Overall Winner**: Best clarity across both divisions
+
+#### Judging Criteria
