Tolerance Test

Tolerance Test – Hexagonal Fits (0.00 to 0.40 mm)

This **tolerance test** is designed to accurately calibrate the **fits and clearances** of your 3D printer using a series of **hexagonal holes** with different tolerance values.
 

The model includes several numbered fits, each with a progressive tolerance increment, allowing easy identification of the optimal fit based on your printer, material, and print settings.
 

🔩 Design Features:

• Hexagonal fits with progressive tolerances:
  0.00 / 0.05 / 0.10 / 0.20 / 0.30 / 0.40 mm
• Numbering engraved on the part for quick identification
• Compact design, quick to print, and easy to analyze
• Ideal for testing **press fits, sliding fits, or functional tolerances**

🧪 How to use this test:

1. Print the model with usual material parameters (PLA recommended)
2. Test a standard or custom-designed hexagonal piece in each hole
3. Observe what fit is achieved:
   • Too tight fit
   • Perfect fit
   • Loose fit
4. Use the result to adjust the **XY compensation / horizontal expansion** in your slicer

📐 What is this test for?

This test is especially useful if you design:

• Mechanical parts with exact fits
• Nut holders or hexagonal housings
• Functional parts that require dimensional accuracy

Each printer and material behaves differently, so this model will help you understand **the real tolerance of your setup** before printing final parts.
