My completed files for the Traveler's Judgement 5 legendary Lost Prophesy sidearm from Destiny 2. These files have been modified by myself from the in-game model, aquired from destinystlgenerator.com.
Not every piece is perfect, as I am by no means experienced at 3D modeling, but I have made some necessary changes to translate the game file into a real-world object that respects the laws of physics.
This has also been resized from the in-game model to bring it more in line with the size of an actual handgun. It measures about 29cm long, and the longest part is about 14.2cm so it should print on fairly small printbeds. Guardians apparently have massive hands, so if you want it closer to the actual in-game size it would probably need to be scaled about 20% larger, but it fits my average man-sized hand quite nicely.
The model includes a removable magazine (ready to be held in place by round 1/2'' x 1/8'' magnets), and is designed to be assembled with 1/4'' dowels as well.
NOT INCLUDED is the tubing, and the wrapping for the grip. I felt these would best be finished with other materials separate from the printed model. I used 1/8'' clear tubing, as well as paracord and hockey tape for the grip.
