Toy Animal Fence

My daughter wanted a fence to make pens for her plastic animals. So I designed and printed something for her.

As a beams, use standard 3 mm struts. The `ToyFence_center` parts make them stand up. The `ToyFence_end` part is attached with hot glue or superglue.

The `ToyFence_Conn_*` parts are connectors of various kinds, allowing to make bigger pens.
