Good day!
Here's a Halo Ring model that I designed myself now many years ago. Though I found you cannot find a lot of Halo Ring models online for printing (or I'm just blind) so here's my version! It is based on the Halo CE Anniversary model.
You will have to cut the ring apart yourself, since I don't want to specify on a size per part due to different build plates. I recommend meshmixer or fusion for seperation.
If you like the model, have any complaints, suggestions or feedback - please let me know!
