A snowball or ball thrower that is modeled after a xistera, the thrower from the game Jai alai.
I would print this on low quality .3 and 5% infill. I have not been able to print a full scale one, but the small scale printed well. I have made a few changes since printing the small scale to make it more user friendly. If you print please post a picture! There is a wide and a narrower version. Make sure that both base parts touch the build plate, a raft might be needed if you are printing small. There is also a smoother version with less of an end curve. You may need to print with minor supports.
