Promethean Activpen 3 Holder

This pen holder is designed to hold a Promethean Activpen 3 and be able to attach to a lanyard clip. This is done with a cut extrusion at the top to allow it to connect to a lanyard clip, which allows the pen to be carried around a person's neck, as a necklace.

The pen holder was designed to fit a Promethean Activpen 3 but may serve other smartpens and pens, if they have similar dimensions and shapes. To create the correct fit for another pen, it may require that you scale up or down the pen
