How to make a clone machine with time interval?

I am trying to make a cloning machine where the "clones" will spawn on a part named "Part" at every X time interval(eg. 3 secs). But it seems not be looping(the script).

local zombie = game:GetService("ServerStorage").AssortedCrystal115

local spawner = script.Parent


wait(0.1)
while true do
    wait(0.1)
    local zom = zombie:Clone()
    local root = zom.HumanoidRootPart
    root.CFrame = CFrame.new(spawner.Position) + Vector3.new(0,math.random(1,3),0)
    zom.Parent = workspace.Clones
    print("Assorted")
end

Thanks.
