Fix Pipboy clipping issuse on armor

[nightwing100]

I know this is very very old issuse but there is just one armor i want to fix by making new model to let it fit on pipboy.

 

Before you ask yes i know i can just use Readius and forget it, but i really don't like readius and prefer the classic handmount pipboy.

 

Suppose i should use tool like Blender or 3D Max to fix it but i'm complete unfamilar with those thing, so if anyone can get me some instruction would be great, basicly i want to edit mesh on the left arm to make it simple.

 

The armor i want to edit is the BNB Black Widow on Nexus by the way.
