Brittle plastic hinge broke after a few months, reverse engineered and printed. Worked great first run.
I trimmed the clip from one side, so it would print flat. I figured seeing this in place would give me a good idea of how to re-design the clip, but it's a snug fit, so it works perfectly as-is. If it breaks I'll re-design it.
update one, made a bit taller, and thickened the side with the clip for a stronger hold.
I've been having issues with bridging, so I included support ribs, they snap out easily.
