These are simple display stands for Jakks Pacific Legend of Zelda (Breath of the Wild) figures. Zelda has a tendency to fall over, so this stand will help keep her vertical. A similar stand was made for Link. They have different sizes of feet so they have unique stands to accommodate.
A nice little Triforce relief was included. Because why not.
This is a re-post of my original upload on Thingiverse
Tree supports for the foot brace work pretty well.
The author marked this model as their own original creation.
