I couldn't find an EVA 3 mount for the Orbiter 2 anywhere, so I edited the LGX Lite mount to be able to fit the Orbiter. Could be a better fit, but it was quick and it works!
This is mainly for printers running the Eva 3.x platform, which I think are just RatRig V-Cores at the moment.
The Orbiter mounts will screw directly into the model, which secures it. You could probably do heated inserts too if u want more stability.
Update (3/9/23): Looks like there is an official EVA 3 design for the orbiter 2, but was not searchable because the design is called “EVA 3 - Modular 3D Printer carriage platform”. So, you probably want the official version rather than this one :) Here is the link!
