QuadraCopia (updated 09/15/18)

Update 09/15/18: Added updated model, quadracopiasqrupd.stl, for the square version to eliminate small points at the top and bottom. Another solid sculpture that requires printing in Corkscrew/Vase/Spiral (single wall) mode with no top layers, but five bottom layers. You can also turn off vase mode and set it to print two or more side layers, zero top, and five bottom layers. I used PETg on my Taz6 and PLA on my Orig Prusa i3 MK3. There are two versions available here. One features a cross pattern on the ends, while the other is more square in design. The ones illuminated in the photos are turned upside down and utilize an LED base from my HexaFloraDeLuz design.
