REVOMAZE Lite

If you would like a copy of the print its on the link below in the first comment

Hello. In the regular Revomaze, there's nothing sticking out from the side, but in the lightweight version, there's a cylinder. Today, I tried to open the blue Revomaze and drew a detailed diagram, but all the steps led me to a dead end. How can I determine if the lightweight version is ready for opening? Can anyone provide guidance based on the diagram? Do I need any tools for disassembling and assembling the product? Is there a certificate for the aluminum cores?
