<p>I tried out printing a "bridge" for the first time using this <a href="https://www.thingiverse.com/thing:284380" rel="nofollow noreferrer">Bridge Calibration model</a>. The model creator suggests printing, tweaking settings, and printing again until it works "properly." </p>

<p>My first try worked reasonably well, but the underside of the bridge is pretty rough and stringy. But I don't know what a "good bridge" is supposed to look like.</p>

<p>How smooth should the underside of the bridge be? Any suggestions for what changes I should make to my slicer settings? Here is what I have currently:</p>
