Summary

F.A.Q

You can sell your prints on Etsy etc.

Don't ask me for a permission, instead read a License on a left (it's CC - Attribution SA)

I don't need your cut. Instead if you like a model or you making a profit out of it - donate me a small amount.

1. License is for a 3d/STL file and NOT for a PHOTO / other content
   (you can't sell your prints using my photo, do your own photo of your print).

DESCRIPTION:

Just a couple of modifiers to give Honeycomb vase(by radus) more stable bottom. Also i think it looks more organic. Done in Blender 3d, .blend file is attached.

[sotvl_Spiral-Vase.stl] is a solid shape. you should print it in "Spiralize Contour"(Cura) or "Spiral Vase"(Slic3r). Ts is not waterproof, as it will be small holes on a way up from bottom. So, it is not good for water, but soil is ok.

[sotvl_thick 1,2mm] - with a proper thickness calculation. 1mm and 2mm thick respectfully. probably waterproof... but not tested by myself with a print yet. Slice and print as a usual thing, not in vase mode.

[sotvl_thick-Blender.stl] is thick/thin shape. should be ok for usual print and waterproof, but need more testing with prints. At current state, it seems it less reliable compared to sotvlthick 1,2mm.

[sotvl.blend] - source Blender3d file, shape and thickness can be changed there. (for advanced users)
