Twirled fluted vase

This vase is designed to be printed in like-vase-mode but not in actual slicer vase mode.

The design is an offshoot of my finned planters

The design is optimized to print on larger printers like the CR-10 as it will only slice correctly when scaled close to it's native 400mm height. You can go down to 300mm but much lower than that and you will get gaps in the walls. Those can be removed by setting a small nozzle size or allowing bigger overlaps in the slicer. You will also need to reduce your layer height if you scale down to ensure the overhangs print nicely.

In simplify3d I use 3 processes to make the slicer behave itself.
One for the bottom 5mm, one for the top 5mm and one for everything in between.

I printed it with a 0.40mm nozzle, one outline, no infill and 0.2mm layer height.
Material is Silky Copper PLA (just plain shiny pla, no metal fill) which gives a nice shine and also gets fairly dark in the shadows. Also tried wit
