title: End Drilling
summary: I 3D-printed some jigs to help drill holes into the ends of boards

<p>Now we can drill 5/16" holes into the ends of two-by-twos with confidence!</p>

  (note that these both <code>use</code> another SCAD file in that repository,
  so it's probably best to check out the entire thing)</li>

</ul>

<p>I like that Thangs and Thingiverse make nice previews of my models,
but uploading all the files to them is kind of a chore,
and both of the sites are a bit flaky.
Thangs.com really wants to say my model is a 'Character' (category),
and Thingiverse likes to show outdated version of my description,
and its customizer crashes with a "parse error in line 111".
It probably doesn't help that I shoved two separate OpenSCAD objects into one Thingiverse item.</p>
