How would you make a dropper with this script have a texture to go along with the mesh?

wait(2)
workspace:WaitForChild("PartStorage")


deb = true 
script.Parent.Clicker.ClickDetector.MouseClick:connect(function(wat)
	if deb == true then
		deb = false
			local part = Instance.new("Part",workspace.PartStorage)
			part.BrickColor=script.Parent.Parent.Parent.DropColor.Value
			part.Material=script.Parent.Parent.Parent.MaterialValue.Value
			local mesh = Instance.new('SpecialMesh', part)
			mesh.MeshId = "157813031" --What you want or what settings you want.
			local cash = Instance.new("IntValue",part)
			cash.Name = "Cash"
			cash.Value = 5 -- How much the drops are worth
			part.CFrame = script.Parent.Drop.CFrame - Vector3.new(0,1.3,0)
			part.FormFactor = "Custom"
			part.Size=Vector3.new(3, 3, 3) -- Size of the drops
			part.TopSurface = "Smooth"
			part.BottomSurface = "Smooth"
			game.Debris:AddItem(part,20) -- How long until the drops expire
			wait(1)
			deb = true
	end
end)
