One of those questions that keeps coming up about the Egg-Bot is, “Does the surface have to be perfectly smooth?” Or sometimes just, “Can you print on a golf ball?”

While we wouldn’t go so far as to say that you’ll have good luck printing on a tennis ball, it turns out that the surface doesn’t exactly have to be flat either. Golf balls certainly aren’t a challenge. And, as you can see above, you can even plot on strangely shaped “eggs,” so long as the surface is smooth enough that you can drag a marker along. Neat.

Update: We’ve posted some tips on using the Eggbot with pumpkins here.
