For fun today I was playing around making a clasp that would snap perpendicular for use with signs or jewelry. The first version is working well and appears to have good holding power. I think you could use one or more on a larger sign without much trouble. With a little modification one could string some Christmas ornaments together. The nice part is the sign just needs notches so if the “spring” part breaks it’s easy enough to try again with another print. Thought I’d share if anyone else wants to play around with the concept.
UPDATE: I just noticed my original upload was 3.4MB! I investigated and found an embedded image from a while back that Inkscape never cleaned up or would show in the UI (I deleted the layer it was in). I removed it with Inkscape’s XML editor (wanted to try that) and I uploaded the file below. I’m keeping the original file as an example of things to watch for when using Inkscape! Both files load in the GFUI fine – the first one just takes a lot longer!
I’d recommend paying close attention to grain direction when you position the cut. With such thin clips, you’ll want to make sure that the wood grain runs perpendicular to the pressure that will be applied to it.
Good point when using it with hardwoods. When using with the ply though it shouldn’t matter since grain direction alternates in traditional ply and in proofgrade it is an mdf core.
