This is a remix of MakerBot's awesome Ram Skull https://www.thingiverse.com/thing:473590
This thing is MASSIVE!! I used 5 KG of filament (2 white for the skull and 3 tan for the horns).
I made this for my daughter so it may not fit a large adult. It just barely fits me. Because of the weight, I don't recommend this for small children.
I moved the eyes to the front for obvious reasons. Now it looks like a hybrid of human and ram skull.
I glued memory foam to the top (for the top of your head) and glued felt over it and on the rest of the inside for comfort. (see 4th picture)
If you print at higher resolution, it will take forever to print. It looks very good at 0.35. The longest part to print was 30 hours and there are 16 parts.
I did the infill at 5% to keep it as light as possible. It comes out perfectly.
Do not do less than 4 perimeters or the pin holes will break when assembling it.
