Pen Ball - Phiên bản in TPU

This is sized for a standard pencil.  Since it is designed to be printed with TPU, it has an internal ring that is a little smaller to snuggly hold the pencil.  The ring diameter is 7mm which should be slightly less than the max diameter of the pencil or pen.  Scale entire ball accordingly for larger or smaller diameter objects.

To prevent overhang drip, this has a beveled tip which seems to make it a little easier to use as well.
