Skully - Animatronic Skull

Decided to create an animatronic skull for halloween!

This motion control is inspired by this video by Bottled Lightning: https://www.youtube.com/watch?v=FwPx53iEUiY
I thought I'd try making the servos part of the UV mechanism itself.

Printing:
I printed this on a 150mm by 200mm print bed
When printing the top of the head I chose zero bottom layers, no infill and 3 perimiters to get a hollow part.

Assembly:
I hollowed out the skull this is remixed from and made room for some servos..

The mandible is attached by drilling holes in the bottom of the skull and through the upper part of the mandible, and another small hole is drilled to attach fishing line to a 9G servo mounted to the underneath of the plate.

There's a hexagon shape for a 5/16" threaded rod coupler, which is attached to a threaded rod, I use it, some nuts and a bracket attached to an old chair to hold the skeleton in place, with the little neck disk to help hold the skeleton
