Laboratory Power Supply Unit Case/Box for DP20V/2A Power Controller

I have designed a simple and small Case/Box for the Power Controller from Banggood. The Controller is available with 20v/2a and 30/3a, but has the same size. For building up do you need 6xM2 Screws, a Notebook Power Supply Unit and some kind of Plugs.

On Youtube i have uploaded a Tutorial with Review and Function-Test, but it's in German.
