Mechanical carrying case for knife prototypes

This is a carrying case I've made for the Utility Knife prototypes. I wanted something more presentable than the Ziploc bags I was previously using when taking them to conventions and meetings. I like making fun mechanical boxes. This is a pen box I made a few years ago. The carrying case uses cams and linkages to smoothly raise the knives as the lid opens.
