This pencil, or what-not, cup can be printed in vase mode or spiralize outer contour in cura, or printed in normal mode. You can uncheck spiralize out...er contour to print in normal mode, set top layers to 0, set infill to 0%. Bottom layers set to 3 or more. Set walls to 1 or 2 or more for a more sturdy vase if not in vase mode. Can be scaled to fit your needs. The vase in the photo shows vase not scaled at 100% of the stl file at 100mm wide for X and Y and Z is 113mm tall. It has not been tested for being watertight and probably isn't printed in vase mode. If you make it, please post a photo, I'd like to see your print!
NoTEs .....look below...
3d model print parameters
....The stl file IS NOT hollow.....
Use 0 top layers, 0% infill if not printing in vase mode. I used a .4 nozzle, wall line width of .8 and a layer height of .2 other widths might work, I haven't tried them. The print should take approximately 1 hour 45 minutes at 50mm/s using vase mode.
