Tycoon: How to resize a mesh for a block in a dropper?

I was able to get the mesh substituting for a block from a tycoon dropper. I am now trying to figure out how to resize the mesh, so when it spawns it is much smaller. I am currently using this script~

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 cash = Instance.new("IntValue",part)
			cash.Name = "Cash"
			cash.Value = 1 -- 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(1, 1, 1) -- Size of the drops
			local mesh = Instance.new("SpecialMesh", part)
			mesh.MeshType = "FileMesh"
			mesh.MeshId = "rbxassetid://507468593"
			mesh.TextureId = "rbxassetid://507468594"
			part.TopSurface = "Smooth"
			part.BottomSurface = "Smooth"
			game.Debris:AddItem(part,20) -- How long until the drops expire
			wait(.15)
			deb = true
	end
end)

I tried adding this piece of code, but it did not work.

m.Scale = Vector3.new(2,2,2)

Does anyone know how to do this, or have a link on how to do it? Thank you!

The answer is "Scale" but if it is a costum mesh you better should work with smaller values example:

mesh.Scale = Vector3.new (0.2,0.2,0.2)

smallest you can go is 0,01 I thought. I hope this helped your problem also if you did used "m" it wouldn't worked because your local is mesh.
