Two Card Badge Holder

This is a badge (or employee ID) holder with a location for a second card. Some workplaces have separate cards that act as keys for specific locations or systems. The second card key is easily removed so it can be inserted into a card reader if needed.

The voronoi pattern so every time you regenerate the design in OpenSCAD you will get different voronoi pasterns

The pictures may look a little distorted but the design is for standard, credit card sized, cards (3 3/8" x 2 1/8").
