This is the file that AnyCubic provided to print for their Kobra series of printers launch in March 2022.
The STL is the original file. I also uploaded a rotated and scaled the model to fit on the Mini & MK3S+. These versions also have a custom raft under the end of the tail and head sections for stability and bed adhesion. You can delete them in PrusaSlicer if so desired.
The author hasn't provided the model origin yet.
