I'm hoping that someone can point me in the right direction if I am heading the wrong way....

I need to trace an object (lets say it's the size and shape of a gun). Normally I would use a thin pencil to trace the object as precisely as possible. Maybe it's thee age or my eyes are going bad but I am not able to get the precision that I used to be able to.

I am looking for a solution similar to a reaction arm. but instead of a screwdriver at the end I would have some kind of an attachment for a pen or pencil and the reaction arm would keep that tracing material perfectly vertical thus giving me a precise and accurate trace of the object (as described above).

There is an example of the type of reaction arm I am referring to (if my pic doesn't show). It's the center arm of the three pictured.
