I ran off a few patches of miniature chain mail for holiday handouts to a few folks who’d appreciate them:
Chain Mail Armor – 6×6 9.6 mm – top view
A little patch like that makes a fondletoy that’s easier to pocket than, say, a planetary gear bearing and should be robust enough to withstand quite a bit of abuse.
Alas, it turned out that recent Slic3r development versions suffered a bridging regression. The stable 1.2.9 version does the right thing:
Slic3r 1.2.9 – good bridging
The hot-from-Github version goes diagonally, producing a pattern like an internal layer that normally sits atop the (omitted) bridge layer:
Slic3r 7c8b710 – diagonal bridging
While that might barely work, the little bitty link bars will certainly fall into the abyss:
Slic3r 7c8b710 – diagonal bridging on links
Given the complexity of slicing algorithms, I definitely can’t track down the problem; using the stable version for a while should suffice.
The OpenSCAD source code as a GitHub gist:
