Silhouette Plotter Ball Point Pen Refill Adapter

This thing is for Silhouette Portrait Plotter, it holds a ball point pen refill, so you can use it with the plotter for either writing or with an older one, not writing anymore, to do the folding edges of your design.

The design incorporates two springs - the tension is adjustable with the crew on top.

Depending on the used refill you might have to adjust, how far you lower it into the plotter before locking it. I added some spacers to print, so you have it easier after the first try.
