@chesslover0003 - perhaps if you buy a spool of wood filament and donate it to the library after you've printed a few sets they might be happy to accommodate you? You should be able to print around 3 complete sets (34 pieces each) with a 1Kg spool of PLA filament. Wood-stain varnish works well to convert light wood pieces to black pieces.
I've offered this exact thing too. I'll keep working on them. I'm at another library printing now... I'll see how they take the suggestion.
