Chess turn indicator

Turn indicator for "Open Chess". By "Open Chess", I mean a chess board set up in a public place, for any passerby to make a move. (not recommended during a pandemic)

Rules of Open Chess:

• Anyone can make a move
• Don't play twice in a row - that is, if you make a move for black, don't immediately make a move for white and vice versa
• Update the turn flipper to indicate whose turn is next

How to assemble:

• Print "move for white" side in white PLA, and the other two parts in black PLA
• Smooth parts as necessary
• Cut the ends off a 3 penny finish nail and file the ends so they aren't sharp. This is now the axle. (Photo attached of the box of nails I used)
• Make sure the paddles fit around the axle and the axle fits into the base
• Use a black sharpie to highlight the raised letters on the white paddle
• Use a white paint marker to highlight the raised letters on the black paddle
• Glue the paddles together with cyanoacrylate glue, using the axle to align them. Be careful to not get glue on the axle. Remove axle and let glue cure.
• Slide axle through base, threaded through paddle assembly, into the other side of the base. My print was rough enough that friction kept the axle in place. You may need a drop of glue on one end to keep the axle from sliding out of the base.

Note: in the pictures you can see some magnets stuck into the bottom of the base. But there wasn't actually clearance under the paddles, so I had to sand down the end of the paddles to clear them. I don't recommend using magnets like this; just ignore the circles in the base.
