Grid Placement system, Model Tilted Sideways?

Hello,

I have recently been making a grid placement system but for some reason, the models are sideways and I can't figure out why.

The models aren't sideways when in edit mode but when I play it goes sideways.

Code:

local mouse = game.Players.LocalPlayer:GetMouse()
local Model = workspace:WaitForChild('ManaquinPose1')
local posX = mouse.Hit.X
local posY = mouse.Hit.Y
local posZ = mouse.Hit.Z
local gridSize = 1
local Rot = 0

local function rotate()
	Rot = Rot + 45
	Model:SetPrimaryPartCFrame(Model.PrimaryPart.CFrame * CFrame.Angles(0, math.rad(Rot), 0))
end

mouse.KeyDown:connect(function(key)
    if key == "r" then
    rotate()
    end
end)

local function Snap()
	posX = math.floor(mouse.Hit.X / gridSize + 0.5) * gridSize
	posY = mouse.Hit.Y
	posZ = math.floor(mouse.Hit.Z / gridSize + 0.5) * gridSize
end

mouse.Move:Connect(function()
	if mouse.Target.Name == 'Floor' then
		Snap()
		Model:SetPrimaryPartCFrame(CFrame.new(posX, posY + 3.3, posZ))
			Model:SetPrimaryPartCFrame(Model.PrimaryPart.CFrame * CFrame.Angles(0, math.rad(Rot), 0))
		mouse.TargetFilter = Model
	end
end)

local function Place()
	if mouse.Target.Name == 'Floor' then
	local WindowCopy = game:GetService('ReplicatedStorage').Objects.ManaquinPose1:Clone()
	WindowCopy.Parent = workspace
	WindowCopy:SetPrimaryPartCFrame(CFrame.new(posX, posY + 3.3, posZ) * CFrame.Angles(0, math.rad(Rot), 0))
	mouse.TargetFilter = WindowCopy
	end
end

mouse.Button1Down:Connect(function()
	Place()
end)

Thanks!
