A Bullet Journaling template

Bullet Journaling! It's a thing! And it's a thing that Mickey and I have both had much success with (see my first post on the subject as well as several more on that blog). Mickey has switched to a weekly layout that suits her needs better, using a template we had lying around. This template unfortunately is long enough that it doesn't fit in the journal itself. So of course I took it upon myself to print a new one, also because it's a very simple thing to design. By making a module that does a generic "arrow" that can optionally have one outwards tip and one inwards tip, it was trivial to make this design:

A first print turned out to need enlargement because small features aren't that precise. More interestingly, the top layer was nice and flat in the large areas, but was over-extruded in the little parts between holes.

Between the parallel slats the edge is fine but the in-between is over-extruded due to going back and forth very quickly

I reduced the infill (at 50% from an earlier experiment) as well as the infill/perimeter overlap, but I suspect this is one of those things that requires changes to Slic3r, to adjust for very short back-and-forth lines.

For a second print, I also lowered the Z-offset a bit to avoid elephant foot that was closing up the slats. That was, of course, the wrong thing to do - it doesn't lower the plate, but the hotend, so I got even more elephant foot. Stomp!

The third print came out better, though still has some of the openings that should match a line distance not quite do so. Also, there's a huge blob in one of the slats. Anyway, it's just mere tweakings from now. The extra extrusion in the narrow parts is still there, but I'll just live with it.
