This is a remix of Fernando Curutchet's ELEPHANT DRYER (@FernandoCurutchet). Credit goes out to him in the 1st place, i just spiced up things..
Modeler fercuru seems to have the same pictures of the original file.
If he's the original designer (i don't know) credit goes out to him in the 1st place.. . i guess i'm in third place now..haha :)
This print will take about 9 hours at 0.2mm layerheight.

To make a voronoi pattern on a model like this i discovered you had to make it a solid first in Meshmixer (first i had no idea). The rest was a piece of cake! .. .if you follow a tutorial about this meshmixer tool (make pattern), you will learn the skill in under 15 minutes.
If you have learned this skill and, you find that you have not enough triangles to work with; try remesh function in meshmixer after you select all objects (ctrl A)..
