These can be used as standalone art pieces, but they were designed to go together with my Decorative Hinged Wall Mounted Phone Stand which can be found here:

The dimensions of the frame match that of the above phone stand.
I've not framed all of the animals from the original creator's design, but have included a blank frame template so that you can add your own designs to it in your slicer if you want.
Simply add small pieces of double sided tape to the back of the frame section to mount on a wall.
