    This is a customizable (parametric) version of the Makers Making Change Pen Ball Holder 10, a 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 can be customized to fit the user.


    A pen or pencil is inserted through the pen ball and is fixed in place by tightening a screw. The ball is held in the hand to make it easier to write.


    The design is parametric, which means that the size of the ball the size of the pen it fits can be modified by changing numbers in OpenSCAD.
