Tolerance Test – Hole Fit Calibration

This tolerance test is designed to help you accurately calibrate your 3D printer’s dimensional accuracy, focusing on hole tolerances.

The model consists of a solid rectangular block with multiple circular holes, each labeled with a different diameter increment (from 0.10 mm to 0.35 mm). By testing which hole best fits a reference pin, rod, or screw, you can easily determine the optimal tolerance settings for your printer and filament.

Features

• Multiple hole diameters with clear engraved labels
• Ideal for tuning XY dimensional accuracy
• Useful for press-fit and clearance-fit calibration
• Simple, fast print with minimal material usage

Recommended Use

1. Print the model using your standard settings.
2. Test each hole with a known-size cylinder, pin, or screw.
3. Identify which tolerance provides the best fit.
4. Apply the result to future functional prints.

Printing Tips

• No supports required
• Use 0.2 mm layer height for reliable results
