Help with parts position

I want the desks to be placed parallel to each other when pressed, and a little more apart like this:

when I turn around, it’s different. I need help fixing them so that they are always positioned the way they are in the first picture.

local UserInputService = game:GetService("UserInputService")
local RunService = game:GetService("RunService")
local Players = game:GetService("Players")

local PartSize = Vector3.new(1, 1, 0)
local PartSpacing = 6 


local function CreateParallelParts(OriginPosition, AmountOfParts, LookVector)
	for i = 1, AmountOfParts do
		local Part = Instance.new("Part")
		Part.Size = PartSize
		Part.Anchored = true
		 
		Part.Parent = workspace
		if i % 2 == 0 then
			Part.Position = OriginPosition + LookVector * (i * PartSpacing)
		else
			Part.Position = OriginPosition + LookVector * (i * PartSpacing) - Vector3.new(-3, 0, 0)
		end
	end
end


UserInputService.InputBegan:Connect(function(input, gameProcessedEvent)
	if gameProcessedEvent then return end

	if input.KeyCode == Enum.KeyCode.R then
		local player = Players.LocalPlayer
		local character = player.Character
		local HumanoidRootPart = character:WaitForChild("HumanoidRootPart")
		local OriginPosition = HumanoidRootPart.Position + HumanoidRootPart.CFrame.LookVector * 5 
		local AmountOfParts = 5 
		local LookVector = HumanoidRootPart.CFrame.LookVector  
		CreateParallelParts(OriginPosition, AmountOfParts, LookVector)
	end
end)

Instead of the Parts being created with a Vector3 origin, you should do it with a CFrame origin. Then, instead of adjusting the Parts’ positions, you can update the CFrame I also think this will make the LookVector code redundant
