Designing Sninges in Laser Cut Acrylic

I’ve been seeing this “zig-zag” living hinge technique all over the web since we covered snijlab’s apparent invention of the method six weeks ago.  “Snijlab-style living hinges” is kind of a mouthful, and since it looks like the idea is here to stay, I humbly offer “sninges” as the obvious, handy portmanteau.

Anyway, we’ve covered designs using sninges a couple of times, already, but so far I haven’t seen much detailed discussion.  Enter Make: reader Kevin Gunn, who’s just published this handy guide describing his own experience to date with designing laser-cut sninges in 1/4″ acrylic.  [Thanks, Kevin!]
