Hex surface vase (spiral print)

There will be no more updates to this page. The new home of this model is now on GitHub where you will find the latest updates and where you can download as much as you want even if you're using an ad blocker.

Old information now follows. Don't read this, just go to the GitHub page and read the info there.

I was sure I saw a model like this on Thingiverse but I couldn't find it, so I created my own. Of course, after printing I somehow thought of searching for ‘honeycomb’ and finally found the thing I remembered, which is similar but different.

This is intended to be printed in ‘spiral vase’ mode. The radius of the models is about 53 mm, scale it up or down as you see fit.

Due to the many facets this looks particularly nice in shiny filaments, like the ‘silky copper’ from 3D Eksperten as shown in the photos.

‘Spiral vase’ mode (as it is called in Slic3r and PrusaSlicer) has different names in different slicing programs: Cura calls it ‘Spiralize outer contour’ (may need to be activated in the preferences), in S3D it is ‘Corkscrew/vase’. It is not mandatory for printing this model but provides the nicest result when printing with a single shell.
You can also print it without spiral mode by setting infill to 0% and zero top layers. This allows to print with more shells for extra strength, but it will produce a visible seam unless you enable random contour starting points in your slicer.

For a really smooth finish on smaller prints, print in spiral vase mode with 0.1 mm layers. 0.2 mm is good for larger sizes.

The 0.2 mm print in the comparison photo has some artifacts because the ‘ensure vertical shell thickness’ option was enabled in Slic3r, which may cause it to switch back to regular layers at random points. Make sure this option is not enabled when printing in spiral vase mode.
