Blender is a free 3-D software that lets you create whatever model you want. Its difficulty is based on how well you know the hot keys. I like to use this program a lot with Garry's Mod to see how well I can make body armor or some kind of car part. I spend most of my time learning more about blender and what I can do with it.
