This is a remix to give the clip a countersunk screw hole. I can't point to offsite for remixes for some reason, so here is the original:

I love these clips, but I find certain situations where zip-ties and double-sided tape just won't cut it. There are other clips out there with screw holes, but I prefer this clasp design as it has perfect tolerances at all resolutions I have tried. Its a fabulous design, with just the right amount of grip.
