- Description: Design parametric 3D-printed dice and test for fairness through statistical analysis.
Design Concept
- Dice specifications (size, material, infill):
- How will you ensure uniform weight distribution?
- What design details will your dice include (pips, patterns)?
Design Specifications
| Parameter | Value |
|---|---|
| Die size | |
| Infill % | |
| Material | |
| Pip depth | |
| Pit/pip count per face |
Fairness Testing
Test Setup
- How many rolls will you conduct? (minimum 100)
- Rolling surface and method:
- Date/time of testing:
Roll Results
| Face | Frequency (out of ___ rolls) | Percentage | Expected % |
|---|---|---|---|
| 1 | 16.67% | ||
| 2 | 16.67% | ||
| 3 | 16.67% | ||
| 4 | 16.67% | ||
| 5 | 16.67% | ||
| 6 | 16.67% |
Statistical Analysis
- Calculate chi-squared value or deviation from expected:
- Is the die fair (within statistical tolerance)?
- What face appears most/least frequently?
Reflections
- Were you surprised by the results?
- What design factors influenced fairness?
- How would you improve the dice design?
- What did you learn about manufacturing precision?
