Upcycled PET bottle vase inspired by: http://www.designlibero.com/portfolio/3d-printed-vases-collection/
Should fit standard 38mm bottle (e.g. Gatorade).
To assemble, you just put the PET bottle through the opening at top of the vase shell, screw on the cap and fit the cap onto the shell. Voila!
0.3mm, 25% in fill. No raft and no support.
