About this 3D model

Up until now I've been using a drill press vice to hold circuit boards during soldering. The problem is that that type of vice is a hard clamp and won't hold the board well unless you squish it hard enough to risk damaging the board. So I designed a super simple model based on springs that will effectively hold pcbs firm. I thought about adding some more features but decided that simple was best here. Attached is a pdf drawing for those of you who want to make custom jaws.
