This is an 8 filament hub to use 2 ACE Pro filament stations with up to 8 colors or different types of filament.The box was labeled as an OEM hub, even though the brand was listed as another.It is exactly the same as my Anycubic filament hub.You remove the four filament hub, and replace it with this hub, using the included mounting screws.I got this as a spare, it fits and works perfectly! Same quality, design, and style as the original.wildcard
