-Updated most of the parts slightly and added them as _V2
The issue with the original parts is that the rings don't allign properly in height and it is a bit difficult to assemble. The new Frame_V2.stl has some recesses in the back for that now.
A frame for a gastank i build out of spare parts.
Not completly happy with it but i couldn't lay my finger on the reason.
Maybe i add a platform for the top later, but i didn't suceed in making a good looking walkway yet.
