ScrewBall Toy Extended

I made ScrewBall Toy by millercsm for my toddlers and they liked it, but I wished the bolt was longer, so I used openscad to chop it up and combine 2 versions.

I had some trouble because openscad didn't like the original ScrewBall_Toy.stl. I tried fixing it in meshlab, but nothing worked. I ended up using https://tools3d.azurewebsites.net/ to fix the .stl, and then using 3D Builder to convert from .3mf back to .stl. Then finally I scaled it down a bit in my slicer software so it fit in my 3D printer. Works great!
