How to make the cloned model stay on mouse position?

I've been trying the whole to implement this,

whenever i clicked the button the model is cloned in the mouse position, but how will i be able to make it stay on the mouse position until mouse is click again.

local mouse = game.Players.LocalPlayer:GetMouse()
local ply = game.Players.LocalPlayer.Name

a = game.ReplicatedStorage.TestModel:clone()


script.Parent.MouseButton1Click:connect(function()
    a.Parent = game.Workspace

    game.Workspace.TestModel.plyName.Value = game.Players.LocalPlayer.Name


    a:MakeJoints()
    mouse.TargetFilter = a


    a:MoveTo(Vector3.new(mouse.Hit.p.X, mouse.Hit.p.Y + (a:GetExtentsSize().Y / 2), mouse.Hit.p.Z))
    a:MoveTo(Vector3.new(mouse.Hit.p.X, mouse.Hit.p.Y, mouse.Hit.p.Z))
    target = game.Players.LocalPlayer:GetMouse().Hit


    print("cloned")

end)
