What a great how to Stewart.

Yourself and others may or may not find this drawing of use for future rollerballs, for the internal geometry of the section. It will allow the refill to protude by 3.5mm. The element that is 3.4 i/d is not a critical diameter - you could just as easily make that whole 11.5mm the same diameter at 2.6, but its presence makes it easier to insert the refill.
