How to make dropper to drop model?

Hello, im making an tycoon, and i wanted my droppper to drop this model I tried all scripts from these pages: https://scriptinghelpers.org/questions/38998/how-to-make-droppers-to-drop-models https://scriptinghelpers.org/questions/44056/how-can-i-make-a-dropper-drop-a-roblox-model-not-just-a-block

and it didn't worked :(. So is there an another method to make droppper drop this model https://web.roblox.com/library/3354511166/Unicom-Bottom

Btw im using this script for dropper:

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

while true do
	wait(2.5) -- How long in between drops
	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 = 10 -- How much the drops are worth
	part.CFrame = script.Parent.Drop.CFrame - Vector3.new(0,1.6,0)
	part.FormFactor = "Custom"
	part.Size=Vector3.new(1.4, 1.4, 1.4) -- Size of the drops
	part.TopSurface = "Smooth"
	part.BottomSurface = "Smooth"
	game.Debris:AddItem(part,20) -- How long until the drops expire
end
`

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

while true do
	wait(1.5) -- How long in between drops
	local model = game.Lighting.Burger:Clone() -- Change burger to whatever you like
	model.Parent = workspace
	local cash = Instance.new("IntValue",model)
	cash.Name = "Cash"
	cash.Value = 5 -- How much the drops are worth
	model.PrimaryPart.CFrame = script.Parent.Drop.CFrame - Vector3.new(0,1.4,0)
	game.Debris:AddItem(model,20) -- How long until the drops expire
end

So basically i quickly made a burger model and used the qperfection weld inside the burger model.

'you can also weld it normally'

I then made 1 of the parts PrimaryParts just to be able to move it with 1 part.

You can change the model to the one you like and put it in Lighting.
