Borderlands 2 is my favorite game of all time. Since I love the game and making things I made this Corrosive Infinity Pistol. In the Sketchup file is the full pistol separated in parts since the gun is about 11 inches long. The gun is hollow inside because I was going to make a mold and put electronics inside, but this took a while for me to make so I may make a mold on the next gun I make. Also, included are all the .stl in case you just want to get printing.
These are the settings I used. By no means do you have to use these, feel free to use whatever. Only some of the parts need supports.
Once I printed the gun I sanded and sanded and sanded... After I was happy I made some markings with a knife to weather it, primed it, airbrushed it, then moved to hand painting. Included is a stencil fro the infinity logo. I made it on a silhouette machine. You can take the image, print it, cut it, then tape it to the model to paint if you don't have this tool.
I started with @AndresQuijas, infinity pistol (https://www.thingiverse.com/thing:2183209). There were some errors in the model so I rebuilt most of the model and separated it into parts small enough for my printer to print. I made the gun as big as I thought it would be from taking screenshots of it in characters hands in the game.
