This is a stand for MustangDave's awesome model at https://www.thingiverse.com/thing:981463, I know Phantasm isn't Lovecraft but I had a lot of space to fill on the pyramid and I do feel that the 'cosmic horror' themes fit well. I like to think of it a a seal that keeps the sphere locked to the base rather than flying off and causing brain draining mischief. I used linuxgeek's https://www.thingiverse.com/thing:4209092 model to fill the space. Hope you enjoy!
