I'm not sure why but my orbiter v2 would collide into the 5015 for all models I could find. (Maybe my fan is wider?) This model allows the fan to be recessed 2mm deeper into the body. The orbiter then doesn't touch the fan.
Thank you to @djos_1475_171511 for providing step files of his model, allowing me to easily make modifications.
The author remixed this model.
This body has the 5015 fan more recessed in (by 2mm). Without this change my orbiter v2 would collide with the fan.
