Secret Geometry (keychain)
If you're into the band TOOL you probably know what this is.
This is my first upload, sorry if not enough info, i'll try to answer any questions.
I added two versions, one is just a square and the other is a round keychain. Eventually I want to make a sort of 3d printed book with multiple pages, each with its own image, like a binder with plastic pages or whatever, you'll see what I mean if I ever get around to it.
