Summary

Just want to share it. My wife needed a nice vase and I used my library to create one with an outside voronoi pattern. OK, the photo of my first try shows, that it did not came out tooo well and the part needs further processing (I am still experimenting with PETG and 400mm/s on a FLSUN V400, which was the printing speed for this part, and it took 7h at 0.2mm layer height with no supports.)
The Scad Script uses my 3D-Voronoi library, which is 15€. If someone is interested in it, just let me know. It cuts out the voronoi islands from a given part, and from a given set of voronio-points along with other parameters like paths-thickness and rounding radius.
Have fun!
