There are 3 dog models, and you can mix them up. This means that every front part can be connected to any back part. It's simply fun to play with them.

You are going to need neodymium magnets as a connecting force (6mm by 2mm). You have to pay attention to put the magnets in the right orientation, otherwise you can't connect the parts to each other.

I used hot glue to glue the magnets inside the hole.

I made 30 pieces of each, you can easily print ca. 10 pieces a time.
