This piece is intended to be printed as a corkscrew, vase mode, single wall layer print.
There is a built in support in the bottom due to the leg separation at 25% of the first layers.
You can also print it with 2 outer layers turning off corkscrew/vase, single wall mode and increasing the wall layers. Leave top layers off (0).
I used .2mm layers on a Prusa i3 MK3, using PLA. 215/60. Keep speed relatively low/medium to avoid defects. The white version in the photo is Prusament, Vanilla White. Great stuff!
