I wanted to add an Orbiter 2.0 to my ender, but I couldn't find any mounting plates compatible with the MINIMUS fan shroud. I put together a couple to use. I don't have the orbiter yet, but these are built to the specs in their .step file and the 3d printed sample mounts fine. I'll update the files in a couple of days when I get the Orbiter.
