I wanted a different look then the existing spectator on thingiverse, so I took the death tyrant someone made and added a sphere for his eyeball. Then I took the beholder by pyrokahd and sliced a few eyestalks off and put them on my new model. Did some smoothing, added some detail and came out with a new spectator.
I'm also still prepping for Lost Mines of Phandelver, so need to continue to look at models that I can customize and print.
EDIT: Was not totally happy with the teeth so reworked them. Curled the lip up a bit, extended the tongue, and added eye slits. I left the old version as well in case people didnt want the eyes integrated.
Scaled down to 50% to print the right size for D&D miniatures
