# Current Challenge: November 2025
# Current Challenge: December 2025
## "Wait, This Was Printed? How Are There No Layer Lines?"
## "Bring Your Test Models"
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!
This month's challenge is all about the models we use to test, tune, and calibrate our printers. Everyone has a favorite "go-to" print—whether it's a Benchy, a calibration cube, a torture test, or something unique you've found.
**Bring your favorite test models to the meetup!**
## Challenge Details
### Materials & Constraints
- **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 x 25mm x 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
- **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. **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
### The Goal
Share what test models you use and why. Do you use them for:
- Calibrating dimensional accuracy?
- Testing overhangs and bridging?
- Tuning retraction settings?
- Checking first layer adhesion?
- Just for fun?
### Submission Requirements
- **Physical Model**: Bring your printed test model(s) to the December meetup.
- **Explanation**: Be prepared to share *why* this is your favorite test model and what it helps you achieve.
- **Physical Model**: Bring your printed 25mm cube to the December meetup for judging
- **Dimension Verification**: Must be exactly 25mm x 25mm x 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
### Voting & Awards
- **Group Vote**: The group will vote on what they think is the **Best Test Model**.
- **Criteria**: Usefulness, uniqueness, or just plain coolness!
## Timeline
- **Challenge Announcement**: November 12, 2025 (at November meetup)
- **Submission Deadline**: December 10, 2025 (at December meetup)
- **Judging Period**: December 10, 2025 (during December meetup)
- **Challenge Announcement**: December 10, 2025 (at December meetup)
- **Show & Tell / Voting**: December 10, 2025 (during December meetup)
- **Winner Announcement**: December 10, 2025 (end of December meetup)
## Creating the Cube Model
### Using the Provided Model
**Download the pre-configured cube:**
- **File Location**: [Challenge Files/November2025/Cube.3mf](https://meetup.fargo3d.com/Fargo3d/3DPrintMeetup/src/branch/master/Challenge%20Files/November2025/Cube.3mf)
- **Pre-configured**: Already set to 25mm x 25mm x 25mm with 2 walls and no top
- **Ready to slice**: Import into your slicer and adjust settings for your printer
### Using Bambu Studio
**Step 1: Add Primitive**
1. Open Bambu Studio to a new project
2. Right-click on the build plate
3. Select "Add Primitive"
4. Select "Cube"
**Step 2: Resize the Cube**
1. Click to resize the cube
2. Set X, Y, and Z to 25mm
### Alternative Methods
- **Fusion 360**: Create square sketch (25mm x 25mm), extrude to 25mm height
- **Tinkercad**: Use cube shape, adjust dimensions to 25mm x 25mm x 25mm
- **FreeCAD**: Create cube with specified dimensions
- **Any CAD Software**: Simple cube 25mm x 25mm x 25mm
## Awards & Recognition
### Awards
- **Smoothest Surface Winner**: Best layer-line elimination straight off the printer
- **People's Choice Award**: Community favorite
### Documentation
- Winner photos for social media sharing
- Settings profiles shared with community
- Technique documentation for learning
