I recently made a nice pen for my wife who suffers from fibromyalgia.
The pen is designed to be easier for her to grip, being a more ergonomic shape in order to reduce the risk of her hands becoming sore.

I created a how to guide for anyone else looking to make a pen like this and published it on the instructables website.

The how to guide has been voted as a winner in there paper competition and I should find out which prize it won later today.
