As I said, , Horse themed book end.
It is made up of two parts.
The main one, the horse's head, and the “lower back plate” for the books.
Just snap the “back plate” to the horse. Otherwise, it will not work as a stand.... :-P
It's set up to need almost no support.
Only one place that really needs support is the place to snap this back plate.
Painted 3mf included :-)
