Voronoi Mosquito Coil Holder

I saw a beautiful Mosquito Coil holder while I was in Penang, Malaysia and decided to make something vaguely similar. Instead of making it from patterned metal, I generated a Voronoi 'cage' of sorts in Houdini 16, and exported it for assembly in Rhino, and then finally as an STL. Here are all the working files.

FYI: I use the top of a tin can in the middle to catch pieces of the coil as it burns, the screw hole for this is part of the print, and lines up to centrally mount the metal holders t
