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.


I used Solidworks to design the pieces and modeled the machining jigs by boolean subtraction.

cool idea.

does the playfield have holes the figures are screwed into?

cause then it would make a awesome chess set for the use on boats ;)

or some other very earthquaky places.

Those pieces look gorgeous! =-O

Would you mind sharing the designs? Do you plan on selling these?


Thank you, I'm pretty pleased with the way they've come out. I do plan to sell sets, cut from various materials, as a minor fund raiser for our engineering department. Drop me a line and we can discuss sharing the design files. I'm also planning a mill engraved board, but I'm having to wait for the new semester budget for software upgrade approval.

Oh, plastic soft jaws. Nice idea.

Exactly! And thanks. . .was hoping it might be a helpful tip.

The STL files might not be all that useful for anyone else, but as a tip I think this is great!!
