This is version 1 of the prototype. I will add some section to support the metal components, because they are flexible and slightly bent they are not close to the outside, so it makes it hard to put the screws in when closed. I will add a section that forces the metal to be straight and ready to accept a screw.
This SLA of course is not dyed and no surface finishing work has been done.
Update: Here are the files for this attempt:
These are the brass press inserts I used:
