Pepakura Help Please - RE: Perfect Dark 'Cyclone' Gun

I'm a major Pepakura noob but I've somehow finally been able to extract a certain gun from Nintendo 64's Perfect Dark that I have been wanting to build. The gun is called the Cyclone and I've managed to get it into an OBJ file. The problem is I can't seem to simply be able to unfold it in Pepakura. The file is a cluster, for lack of a better expression. Some of the folds are so messy and tiny and I noticed most of it is stemming from the trigger area of the gun.

Anywho, I'd love to see if anyone might be able to take a shot at it or at least point me in the right direction.

The OBJ file:

Other files in case they help:

Thanks!
