Here is a Deer Head mode for you.
You can use it for 3D Printing or something like else.
And you got a nice neckless.
Maybe you can sell the model after printing.
It's STL Checked.
No errors, no openings and something else.
It's all Quads no Tri's even.

There is a Turbo Smooth modifier on it. You can remove it if you want to.

Images are rendered in Turbo Smooth - Iteration Level 1. You can use higher levels.
