⚠ READ BEFORE PRINTING: THIS MODEL HAS TIGHT TOLERANCES

This model is dimensionally correct and intentionally tight-tolerance.
If it doesn’t fit, your printer is out of calibration or your process is wrong.
Dry your filament, calibrate flow and XY dimensions, and measure your prints with calipers.
Different filaments shrink differently. Learn what material behavior is before blaming the model.
Bad ratings caused by user error, poor calibration, or wet filament will be ignored.
