Pennywise Book Nook Bookmark holder

I'm trying to find small party favors for the 13 days of Halloween, and when I saw the detail in the Pennywise Magnet I thought how it would make a cool book Nook, then I thought how much filament that might take, and I realized our house hold could use a container for all our bookmarks and I hollowed it out with the intention of putting it on the top shelf. This is still a work in progress and I may add a boarder around the top to achieve a better impression that he's peeking out from within the books. I haven't tried printing this yet, I may thicken the walls before I do, I'll probably add a lithophane image to the side and maybe a light feature. Until then the general idea is a multi functional item. One which works as a book end, an item holder, and a decorative horror piece. If I add the lithophane features it may work as a night light too. Still in the brain storming stage but I may hallow out the head and add a light just behind his eye so it looks like it's glowing. Will add details as soon as I have time to work on it, and as soon as I can run some test prints.
