Ball in cage revised

I like to fix things. So I fixed this:
- reoriented for better print.
- fixed inside of roof to be an inverted pyramid so you do not get a mess when printing the overhang (as much)
- sculpted it a bit to save plastic and add a little more artistry.
Enjoy.
Rev 2
- A little stronger arms (rev 1 worked but is fragile
- higher res sphere (the original one was way too blocky)
- New sphere shaped indents in top and bottom to preven ball from sticking.
Rev 3
- After a tip cleaning, I found that the ball sticks too well to the base when printing so added a little bump to move it up slightly. Recommend scaling by 1.25 (125%) for a good strong print.
Enjoy again!!
