Pen Ball

This is a customizable (parametric) 3D printable writing aid. The pen ball makes it easier to grip a pen, pencil, or other writing utensil and may be useful for someone who has difficulty holding a pen or pencil directly.

The diameter of the ball and the writing utensil diameter are available in different sizing and are able to be customized further if needed. There are multiple sizes available for this device for both the device size and pen hole size.
