Using Ray.new, why doesn't this LocalScript work?

Comments: So this is for a set of lasers, Im attempting to make it so when a single laser piece (using Ray.new) would resize if it found a part.Do rays operate with meshs? Unless Im standing on the part itself the ray will resize the laser to default 250.

RECOMMENDED TO LOOK AT THE PROPERTIES

**Part Properties: ** http://prntscr.com/dnqg3u

Ray Module:

-- Vars --
local CollisionRange = 250
local IgnoreList = {}

-- Add table data --


-- Returning function --
return function(Part)
    local nRay = Ray.new(
        Part.Position,
        Part.CFrame.lookVector * CollisionRange 
    )
    local Hit, CollisionPoint = workspace:FindPartOnRayWithIgnoreList(
        nRay,
        {
            Part.Parent
        }
    )
    local Size = (Part.Position-CollisionPoint).magnitude
    local Offset = (Size/10)
    return{
        ['Size']=Size,
        ['Offset']=Offset
    }
end

LocalScript:

local Model = workspace:WaitForChild("Test")
local nRay = require(script:WaitForChild("Ray"))

game:GetService("RunService").RenderStepped:connect(function()
    for _,v in next,Model:GetChildren() do
        local Data = nRay(v)
         local Size = Data.Size
         local Offset = Data.Offset
        v.Mesh.Scale = Vector3.new(Size, .5, .5)
        v.Mesh.Offset = Vector3.new(Offset, 0, 0)
    end
end)
