Laird's 2 Color OpenSCAD Chess Set

Inspired by the Replicator I've reworked my chess set OpenSCAD code to generate either a one-color or a two-color version of my chess set. I haven't printed it in two colors, so consider it a 'work in progress' until someone prints it.

The pieces illustrate how they move. For example, on the pawn the sphere is the current position, and the cubes are located where the pawn can move forward or diagonally to capture. Pieces that move to specific locations use cubes to mark locations, and pieces that move along a line use a diamond/square shape.

Updated to add alighment cubes in the corners for the two color, so that they can be easily aligned to merge.

Converted the OpenSCAD from inches to mm, to make rendering easier. Yay, parametric code! No more manual scaling in +> mm.

Instructions

Print the files named ..._White and ..._Black merged in ReplicatorG for dualstrusion, and hopefully you'll get a nifty two colored set of chess pieces.

Swap the two colors, print again, and you'll have the opposing pieces.

You can also print one-color versions of the pieces, generated from the same OpenSCAD file; it's the one without White or Black in the file name.

To re-generate the STL files, set 'c' in the OpenSCAD file:

• 0 means to generate the one color STL (same as parent thing)
• 1 means to generate the 'black' STL
• 2 means to generate the 'white' STL

You will also need bitmap.scad.

After you generate the two STL files, you need to use ReplicatorG to merge them for a dualstrusion.

I haven't printed these on a dualstruder yet. Printed one-color, worked great!

Converted to metric units, so no longer requires scaling in ReplicatorG. And tweaked the pieces to be more printable.
