Loved this design from Printed into Existence, but it never sat stable on flat surfaces.
I've sliced off the bottom and set the jaw to 100% infill to improve the stability of the design for display on desks or shelves without a stand.
Supports near the back of the skull have been tricky to get right without using support material, which I know not everyone has access to, so the profile I've uploaded has my manual supports that I've found work best for me.
