QuickSwap-Insert

The Swapper3D can hold up to 25 QuickSwap-Inserts.  Your kit will come with Nickel plated Copper nozzles by default, but the actual nozzle is removable and can be replaced with any E3D V6 compatible nozzle.

This way you can still make use of your expensive upgraded nozzles you already own (i.e. Ruby tipped, tungsten, hardened steel, and different sizes, etc).
