-## "Is it Glass or Clearly Natural?"
+## "Wait, This Was Printed? How Are There No Layer Lines?"
 
-Experience the clarity of 3D Fuel's "Clearly Natural" filament in this transparency-focused challenge! Participants will attempt to create the clearest possible print, testing the limits of clear filament printing techniques.
+Can you achieve the smoothest, most layer-line-free surface finish possible? This challenge pushes your printer tuning, slicer settings, and material knowledge to the limit. The goal is simple but difficult: create a 25mm cube with 2 walls and no top that looks so smooth, people question whether it was actually 3D printed!
 
 ## Challenge Details
 
 ### 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 x 50mm height
-- **Print Mode**: Vase mode (approximately 6 grams of filament)
+
+- **Filament**: 3D Fuel filament (any type: PLA+, Pro PLA+, PCTG etc.)
+- **Nozzle Requirement**: Must use a 0.4mm nozzle (REQUIRED)
+- **Estimated Filament Usage**: Approximately 3 grams (for reference only)
+- **Model Specification**:
+  - **Dimensions**: Exactly 25mm × 25mm × 25mm cube (REQUIRED)
+  - **Wall Count**: Exactly 2 walls (no more, no less) (REQUIRED)
+  - **Top Layers**: 0 (no top surface)
+  - **Bottom Layers**: Standard (as needed for proper adhesion)
+  - **Infill**: 0% (hollow interior)
+- **Print Mode**: Standard FDM/FFF printing (no resin printing)
 
 ### 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
+
+- **Smoothest Surface**: Best overall surface finish with minimal visible layer lines straight off the printer
+- **No post-processing allowed** - cubes must be judged as-printed
 
 ### Judging Criteria
-1. **Clarity & Transparency** (40%): How clear and glass-like is the final print?
-2. **Print Quality** (30%): Surface finish, layer adhesion, and overall structural integrity
-3. **Technique Innovation** (20%): Creative printing techniques to maximize transparency
-4. **Challenge Adherence** (10%): Following material constraints and using supplied model
+
+1. **Layer Line Visibility** (100%): The appearance and visibility of layer lines - less visible is better
+   - All cubes must meet basic challenge requirements (25mm cube dimensions, exactly 2 walls, 0.4mm nozzle, no post-processing)
+   - Winner is determined solely by smoothness of surface and minimal layer line appearance
 
 ### Submission Requirements
-- **Model Compliance**: Cylinder must measure 25mm diameter x 50mm height
-- **Vase Mode**: Must be printed in vase mode (single perimeter wall)
-- **Weight Verification**: Should use approximately 6 grams of filament
-- **Documentation**: Include photos showing transparency (with light sources)
-- **Settings Documentation**: Share printer settings used (layer height, temperature, speed, etc.)
-- **Process Notes**: Brief description of techniques used to achieve clarity
+
+- **Physical Model**: Bring your printed 25mm cube to the December meetup for judging
+- **Dimension Verification**: Must be exactly 25mm × 25mm × 25mm
+- **Wall Count Verification**: Must show exactly 2 walls when inspected
+- **Nozzle Verification**: Must be printed with 0.4mm nozzle
+- **Settings Documentation**: Share your winning settings (layer height, temperature, speed, cooling, techniques)
+- **Process Notes**: Brief description of your approach
