<p>I specifically want to test </p>

<ul>
<li>calibration</li>
<li>tolerances</li>
<li>precision</li>
<li>accuracy</li>
</ul>

<p>I'm having trouble with Print in Place models and I'm trying to find out if there's something I can do to improve my print quality. </p>

<p>The printer I am using is a Kossel clone, specifically a FLSUN QQ and assume FDM printing.</p>

The best place to start looking is to go to
Thingiverse
and search on '
benchmark
'. There are a great many models there intended to test various aspects of printing. In fact you could search for example '
calibration benchmark
' or '
calibration test
' and get more specific examples.
Actually,
here
is a collection I just made today of the benchmarks I thought most promising. Disclaimer: I haven't tried them yet!
