HP Plotter Pen Adapter Height Jig

How to use:

- Take your plotter pen adapter, and put it on your pen loosely.

- Push the tip of the pen into the jig.

- Once the tip hits the bottom, your pen is at the exact correct height for plotting

- Plot!

I have a lot of adapters for HP Plotter pens. Sometimes, the same adapter fits different pens. But getting the height exactly right can be a bore, and I made this jig to help with it.
