Files for Single material FDM and resin printing 

1) raven_and_skull_hollowed_skull.stl

This has the skull and jewels hollowed so a light can be placed inside

2) raven_and_skull_solid.stl

A completely solid model which can be printed as is or hollowed as required.

Both models will work for both resin and FDM printing and will scale well.

I have also included the model hollowed as I used it for my resin print (shown in the pictures) . I tend not to include these as it's so shackled to scale and everyone likes to do their own thing but this time I've received interest in the method. The model:

raven_and_skull_hollow_flatbed_no_supports.stl

I was able to print this flat on the bed with no supports - however, I've had people tell me they used supports under the chest area and shoulders of the bird. The bird is hollowed and drains resin and release pressure out of a hole in his mouth (sneaky). The drainhole/pressure hole for the base can be used to allow access to a wire should you want to light the eyes up.

There are also files for multi material FDM printing:

The glorious example in the pictures was printed by Tom Jackson. FDM prints will require some supports under the wings and chest
