Summary This is an outside light. The design and modeling is done with (onshape)[https://cad.onshape.com/documents/32f4d833a1e4257189549ef3/w/cf1f9b652936913deabcdca3/e/6a731fd1c377157dbddcdaf2] You can get a user and clone it and change it. The voronoi curves are created with meshlab: to create and carve the holes blender to solidify and to soften the curves freecad to convert it back to a format that onshape recognizes as a part after importing I sliced with slic3r and printed on ABS. Still need to review the voronoi part. Probably smaller more, smaller holes.
