Post an image when you're done! I'll be curious to know what anti-twist fixtures you settle on, and how they perform.

Ah, that makes more sense. Hopefully the print comes out alright, it took me a few goes to get an arca-swiss mount printed right. Sounds like you might be better off ditching the shallow cutouts in version 2. :)

Great Mikey, it looks well designed.. you obviously have some experience with CAD!
It looks like you've put threads in both the holes, why is that? I'd recommend having a straight hole just big enough to allow a tripod screw through, and then fixing that screw to the bracket with an e-clip (I can provide a photo if you're not sure what I mean). I'd also be concerned with how that thread lines up with the one in the camera. If you must have a thread there, consider inserting a metal thread. If you google something along the lines of "3D print metal thread insert" there's a really great method of adding metal threads to 3D printed parts just using a soldering iron.
My second concern is, there doesn't appear to be much surface area for the bracket to grip the bottom of the camera. It might be a little bit floppy, I would have opted perhaps not to have those shallow cutouts. I'm speaking from experience here, I've used an anti-slip rubber tape (normally used on flooring) to line a 3D printed camera mount. It flopped from side to side a lot without the tape.. you could also try a spray on rubber coating.
How does the bracket facilitate mounting to a tripod? I've never used an L bracket so I'm a bit clueless here... is that an Arca swiss mount?
