During World War II, US Navy ships were adorned with baskets placed around their ships in various places.  Inside these baskets were floater nets.   In the event the ship sunk, the theory was the nets - supported by buoyant cork floats - would float away from the wreck, allowing survivors to climb in and remain afloat until rescued.   These baskets have been a fixture in photo-etch sets for some time, and now we have a 3D printed set from Black Cat. 

There are six floater net baskets in the set.   Four are "filled" with nets, two are empty.  The floats on the nets in the filled baskets are well defined and look great.   The empty baskets are even more impressive - the mesh of the basket is printed so you can see through the baskets. 

I've always found constructing photo-etch floater net baskets to a time consuming chore.  Nor am I very good at it.  Then, once you are done, you have to fill them with something to make them look more realistic.   I filled my baskets with painted plastic rod on both my North Carolina and Texas builds.   If these 3D printed baskets had been available, I would have certainly used them instead.   It might be a little more expensive than PE to trick out a large USN ship, but the results, depending on your budget, should be worth it. 

This is Black Cat Models set AC350051, Floating Net baskets. They retail for about $5.50 USD, and are available directly from Black Cat Models or some our excellent sponsors.   Highly recommended.
