Sound square - calibration and noise check object
by cosmoose, published
This is yet another test part, a right triangle with legs on X, Y, and one at 45 degrees. Designed to use very little filament, or not be printed at all. Can be used to check relative noise levels of X and Y axes, or squareness of alignment.
Scale the part to fit your print bed when slicing. You may choose to run the printer with no filament, just to check the noise of the axes (a dB meter may be useful). Otherwise, print with minimal infill, then check with a carpenter's square to see how well-aligned your printer's axes are.
