Ball in cage revised

I like to fix things. So I fixed this:

1. reoriented for better print.
2. fixed inside of roof to be an inverted pyramid so you do not get a mess when printing the overhang (as much)
3. 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!!
