Is there any easier way to tween a model?

In short, I was working on a sliding door a while ago. I couldn't for the life of me get the whole model (The door) to move using one script and so I had to tween each individual part and have them all connect to a single click detector. This meant (due to my lack of scripting knowledge most likely) that I had to write a script for every part and tween the parent. This totaled to 9 scripts per door. I know, awful. I was wondering if there was a more effective way of doing this using one script.

This is the script I inserted into each part.

opened = false
local TweenService = game:GetService("TweenService")
local part = script.Parent

local Info = TweenInfo.new(
    2,
    Enum.EasingStyle.Quad,
    Enum.EasingDirection.InOut,
    0,
    false,
    0
)

local open = {CFrame = part.CFrame + part.CFrame.lookVector * -4.2}
local close = {CFrame = part.CFrame }

local tweenOpen = TweenService:Create(part,Info,open)
local tweenClose = TweenService:Create(part,Info,close)

function toggle()
    if opened == false
        then tweenOpen:Play()
        opened = true

    else
        tweenClose:Play()
        opened = false

    end
end

part.Parent.Paper.ClickDetector.MouseClick:connect(toggle)

Any help would be greatly appreciated! Thank you!
