stylus (boogie board, magic sketch board, etc.)
thingiverse
my kids got some "Magic Sketch Boogie Board Doodle & Trace" for xmas, and I knew they'd loose the stylus soon enough, so I made a copy of it. Sure enough, a week in, one stylus was missing. I printed one and it's perfect, it writes well, and it fits perfectly in the slot. I made mine of PETG, but i suspect anything would work. just make certain you file or sand the tip lightly to make certain that it's not rough and it won't scratch the surface. I put the 123d file just in case someone wants to mess with it.
