My son and I have been working on a fun one this past week. We are making one of the chess sets from thingiverse. We are using the classic chess set from Steed maker; http://www.thingiverse.com/thing:34017 and attempting to make our own chess board from TwistedDaylight's designs here; http://www.thingiverse.com/thing:234626 I just finished the black pieces and while I have the black loaded I am printing the pieces for the board right now. Still have to clean up the pieces and then start over in white but its a fun family project. 1/4 of the board being printed. Then white squares will be fit in over the circle areas.
