Ripping 3D Models from Rainbow Six to 3D Print With

[Fallout32]

Hello everyone, I apologize if this has been posted before. I'm very into gaming and 3D Printing. That being said, I really like the models used in Six Siege and would like to have them printed. Unfortunately I have not found a solid guide to manage this. I tried using Mashak's weapon pack on here but I had to decompile it with Crowbar and the file that I got was a bunch of orange lines and not the gun itself. Does anyone know how to properly convert the either Mashak's or the game's files to a working stl format? Thanks.
