Since the World Championships are being played now, i thought i would design a soccerball/football (whatever you like to call it).
It has a lot of overhangs, retractions and bridges, so consider this a challenge. Or a torture test for your printer. Print this with or without supports, without is THE REAL CHALLENGE, and show me the results! I am very curious if you can print it succesfully. (I haven't been able to get it correctly myself yet)
