Browsing the internet today, I found this: https://kanengomibako.github.io/pages/00329.html
Looks like they have mocked up a Boss style enclosure using PCB material, hard to tell for sure. Great work! I love a custom enclosure.Explore this site and translate some pages, there are some great ideas! I need to figure out how they made this enclosure. Post a comment if you have any more information!
