gravity screw extended

I made Gravity Screw by burhop and liked it, but I wished the bolt was longer, so I used openscad to chop it up and combine 2 versions.

To print it, I scaled it down a bit in my slicer software so it fit in my 3D printer. Since it's scaled down, it's just barely heavy enough to spin itself - if I print it again, I'll increase the infill from 15% to at least 30% or more so it's heavier.
