I printed the "Wall" file in Fluorescence Green PLA on an Up Plus with 0.3 mm layer thickness, no support, normal speed.
The green is nearly impossible to photograph ;-)

I am currently printing the "Solid" file on an Up plus at 0.15mm with the 'surface' setting at fast speed. About two hours total time.
This setting results in a single perimeter vase with a thin bottom.
(It automatically removes the top)

Strangely though, the "Shell" file printed on Up plus with surface option does not print the bottom. So Up software is bit funky. This file is for the "Shell" option in Up or the Vase/Spiral vase function in other software.
