So @LeonianUniverse and I are printing a Braille chess board designed by Aravia. We're printing the board itself and its working very well though of course we don't want to jinx it as you never know until you try. We've already printed some good chess pieces that are for the accessible chess set. If there's anyone into #3dprinting, who is #blind and looking for a good chess set that is endorsed by the Braille Chess Association, check out Aravia here. printables.com/@ERAVIA
