Yet Another Vase
I created this as a learning exercise in Fusion 360 but I couldn't resist printing it. The original model had a slight imperfection in the geometry but printed fine.
Version 2 is now much improved in my opinion, same bottom profile as the original but different shape.
Thanks to Tom for printing it first and supplying the photos.
Note that the stl is of a solid model and so you'll need to either print in vase mode or else print with 0 top layers and 0% infill
Should be good for most sensible materials
