Magnetic fishie

This fish fits two 8x3mm magnets inside so other toys such as this otter https://www.printables.com/model/889097-magnetic-otter can hold it.  Unlike the original model this fish is two sided to work better as a small toy rather than a refrigerator magnet.

Printing

 * Use a raft. The model doesn't have a flat bottom and the tail didn't work without a raft.
 * Use 3 walls.  I found that the top of the tail often fell off unless it was strong enough with 3 walls.  but maybe that's caused by how my printer did the pause.
 * Add a pause at the layer where it closes the magnet holes, insert the magnets.  Be careful!  As I inserted the 2nd magnet it would pull the first magnet out again and shoot it across the room.  After putting in the first magnet I covered its magnet hole with my finger as I inserted the 2nd one.  They'll need to be oriented correctly to attract each other.

Joined two fish back-to-back to make one double-sided fish and scaled it up to fit an 8x3mm magnet.
