This is a remix of Gynni's goose from https://www.thingiverse.com/thing:3906053. I made it so the magnet (5x3mm) is hidden a few layers inside the beak instead of being open at the bottom.
To make it, just put a pause in the gcode before the layer that covers up the magnet's hole, put in the magnet, and resume the print. The next layer should cover up the magnet and seal it in. Make sure there are no supports in the hole when you slice it.
Gynni, the guy that made the original goose, gets full credit for the goose model. All I did was download his .stl of the beak and add a hollow part in the middle for the magnet.
