I've made a few models and have decided to release them to the public for use.
These models have no mountpoints so you'll have to add those in yourself. Some of these may be incomplete in other ways as well, but its better than nothing.

WARNING: I apparently didn't apply the mirror modifier. I don't know what effect this will have, but I'd recommend applying it.I took the KTM X Bow and modified it a little bit. Missing mountpoints and tires.
