This is the Revolver of Androxus, from the game Paladins; by Hi-Rez Studios. Fully modeled by myself. Spent a couple of weeks modelling it last year but lost interest in the game (OB64) and never printed it for myself.
Rather than keeping the files to myself I am uploading them for others to enjoy. Feel bad for not doing it until now, but honestly I forgot. I know a lot of the community for the game loved this model when I was working on it via twitter.
You can either print the Barrel the way I have it sliced (top and bottom) or use the completed view of it and slice it yourself.
If anyone prints this I would love to see how it turns out. Enjoy.
