Hey guys! ;D I made this on Cubify Invent, a 3D rendering software. You can get it for free for 2 weeks (I still got 9 days), and it’s very easy to build a profile of an object and revolve it.
The blue parts highlighted in the Sky photo are the out and inside parts of the circle. The gap in between would be intended for weighting of some variety. Similar with the spike set in the middle if additional weighting would be required.
Tell me what you think!
