Funnel vase mode with two wall

Funnel with top diameter 120mm and bottom diameter 15mm.

With a small circular space on the nozzle that allow the air to escape and the liquid to flow smoothly.

The provided gcode has been improved and it's not possible to directly generate it from PrusaSlicer.

It print like in vase mode but with two perimeters.

It need two revolution to rise one layer height.

After the first revolution the Z axis is half the layer height. To perform the second revolution the noozle cross the first one. The second revolution is done 50% inside the first one.

This way of printing ensure better resistance than a simple vase mode and much better waterproofing.

The provided 3mf file got a very thin cut on one side so it can be sliced in vase mode with two perimeters. But the result need to be recalculated to get the same result as the gcode.
