Do some 3D Modelling

I am interested in a 3d model that I can use eMachineSHop to construct a tactical flaslight foregrip. I would like the foregrip to house the battery in the handle so that I can easily put the battery in and take it out to charge. The battery dimensions are here: [login to view URL] This battery need to go into the handle with the wire coming out near the top. The foregrip will connect to my rifle using a picatinny rail. The picatinny rail specifications can be found here: [login to view URL] There should be 2 -3 mounting bolts that secure the grip to the rail. I put 3 mounts in my drawing, but I would actually prefer 2. The diameter of the flashlight will be approximately 35mm, but I should be able to tighten some bolts to secure the flashlight. The length of the flashlight will be about 2inches. I am including my own hand drawing of this. I am also including several pictures to give you some good design ideas. The more ergonomic and creativity, the better. I must be able to upload to emachineshop software, so if you can provide the model in a dxf, iges, stp, or step.
