Lounging Cat altered with http://www.voronator.com/ and tinkercad.
I needed to use the smaller file offered from voronator in order to transfer it to tinkercad and cut the hole in the bottom. A battery powered tea light will fit nicely through the bottom hole.
Voronoization + Tinkercad.
I used cura to scale the original stl to just fit on the bed at an angle and then saved/exported it to my desktop as a STL.
I then used http://www.voronator.com/
settings: -> output settings export as stl. Number of Holes: standard. Thickness of new layer: Standard.
Hole cut out using tinkercad.
