I've been fortunate to have a little time this summer to work on a project or two that are less than mission critical, while still being potentially useful...case in point a custom chess set design that I'd like to make available to support our engineering program, and would like student assistants to be able to manufacture for me. I'd finished the lathe programs for all the pieces and only had the slot in the bishop's mitre and the knight's nose to finish and was wondering how to make it simple. It occurred to me that amongst all the designs that are parametric and flexible for many situations, one of the strengths of 3D printing is to make that single, one-off, ultra custom, just-for-one-purpose piece.

So, here are the custom machining jig parts that simplify finishing the bishop and knight pieces for my custom designed chess pieces.
