Get models to rotate along walls using rays

This is what I currently have for my model placement.

Mouse.Move:Connect(function()
	if IsMoving then			
		for i, v in pairs(Model:GetChildren()) do
			v.CanCollide = false
		end
			
		local UnitRay  = Camera:ScreenPointToRay(Mouse.X, Mouse.Y, 1)
		local NewRay = Ray.new(UnitRay.Origin, UnitRay.Direction * 1000)
		local Hit, Pos, Normal = workspace:FindPartOnRayWithIgnoreList(NewRay, {Model, Player.Character})
		
		local PosX = math.floor((Pos.X / 2) + 0.5) * 2
		local PosY = Pos.Y
		local PosZ = math.floor((Pos.Z / 2) + 0.5) * 2
		
		local NewPos = Vector3.new(PosX, PosY, PosZ)
--[[
		Model:SetPrimaryPartCFrame(
			CFrame.new(NewPos, NewPos + Normal * 15) * 
			CFrame.Angles(-math.rad(90), math.rad(Rotation), 0) * 
			CFrame.new(0, Model.PrimaryPart.Size.Y / 2, 0)
		)
]]
		Model:SetPrimaryPartCFrame(
			CFrame.new(NewPos) *
			CFrame.Angles(0, math.rad(Rotation), 0) *
			CFrame.new(0, Model.PrimaryPart.Size.Y / 2, 0)
		)
	end
end)

As you can see, I have 2 Model:SetPrimaryPartCFrame chunks of code. The one commented out is what I originally had, which works with wall placement, but it screws up my rotation. Then the SetPrimaryPartCFrame that’s actually being run works with my rotation, but if I move a part along the wall it just stays upright instead of rotating to the surface.

This is how it SHOULD look

As you can see, the model is staying upright, instead of rotating along the walls surface.

I know this has something to do with Pos + Normal * 15 but I can’t just do

Model:SetPrimaryPartCFrame(
	CFrame.new(NewPos, NewPos + Normal * 15) * -- SHOULD make the model rotate along the wall + move it to follow the mouse
	CFrame.Angles(0, math.rad(Rotation), 0) * -- Rotates the model based on its current Rotation
	CFrame.new(0, Model.PrimaryPart.Size.Y / 2, 0) -- Offsets the model so it isn't halfway thru the ground
)

As that just screws with my rotation

CFrame.Angles(0, math.rad(Rotation), 0)
