Wireframe deer head

This is a wireframe head of a deer, inspired by various wireframe sculptures, mostly the one from [Dotsan](https://www.etsy.com/listing/268030334/stag-deer-head-trophy-large-3d-print).

The model is rather hard to print if you don't want to have 10 times more plastic in supports than in the model itself. To try to reduce the amount of supports, I've designed custom supports, which are in file "p3" (for which I've enabled "Print as support" in per-model settings in Cura). They worked for me, though they are not perfect. Or just enable automatic supports. Experimental features like tree supports might be good for this model, but I had no success with them.

Regardless of supports, the bottom surface area is tiny, so brims or rafts are better be enabled.

The model is split into 3 parts, each of them fits inside a regular 20x20x20 3D printer. You can even scale it a bit more.
