Great initiative with this project.

1. I agree with the body matched anti-twist features. I used to think 3d scanning would be necessary for getting an accurate representation of shapes with fine dimensions but actually resulting surfaces are likey coarse and might not give you better results than using a simple caliper. Alternatively you may be able to pull vector drawings of the camera from the pdf user manual (open in acad or ai) and scale them to 1:1 for accurate dims.

2. Another tip someone mentioned already, especially if you are printing in plastic which I imagine you are, it might be a good idea to use threaded inserts rather than relying on plastic threads (might not last much)

3. I would also consider dropping the hole where the bracket angles as it looks like it could be a weak point.

4. One last comment, you might need to beef up that area around the central (threaded) hole.

Btw I'm a product designer
I actually will be getting the camera scanned (hopefully) tomorrow. If the resulting model is too coarse, well then I might be sunk. I did add in measured body-matched features a few days ago but I'm skeptical of them. When I get the camera scanned I can double check them and add/subtract as need be. I didn't think of using the manual so I just checked it and unfortunately there are no front facing vector diagrams in it.

I'm not going to be using the printed plastic bracket as the final product, I want to get it CNC'd out of 2024 or 6061 aluminum. I'm leaning more towards 2024 for its better corrosion resistance and better machining properties vs 6061. And that hole has sort-of been dropped. The bracket is now a two part assembly with the "L" and horizontal parts assembled with #5-44 screws.

I can see what can be done with the screw. Probably can remove the circle and make it just a straight bar.

Well no dice on the scan but a new render of the bracket. Like I said, the bracket is now in two parts, the horizontal base and vertical L. Just need to get 2 #5-44 screws. First is another 3D printed prototype at some point. (The blue color is just to make the part visible.)

Well done!

How are the parts connected?

I noticed a few details I think can be improved slightly, might let you know later this week.

They use 2 1" long #5-44 socket head screws.

4/18: Also now just added a safety stop screw hole in the bottom.

From all appearances, I've finished the design. I'm getting a prototype printed and if all goes well I'll fix up a G-code and get it milled from 2024 or 6061 aluminum. Or at least I'll try. I'll post some pictures when I get the printed pieces in.

Got the bracket in yesterday and I'm pleased with how it came out. Now I just need to get it milled out of aluminum.
