Ergonomic Magic Mouse Adapter

Hi, I've a magic mouse but the ergonomic of the mouse is not the best. Willing to buy a new mouse I found a youtube video of someone upgrading his mouse. Unfortunately he modified also the wiring of the mouse. So with his Idea, I found this file on the internet. There were some on makerworld but those didn't please me. Printed with Silk PLA on my P1S. (0.08 extra fine printing profile with supports (Tree (auto)).)
