This is a camera mount I whipped up for my laser engraver. I had some extra pieces of aluminium extrusion I used as a top rail to hang it off. I used Laurenguijts' original design and added my own open bracket.

My use case was kind of specific but hopefully this will help someone in the future.

Can be printed in place without supports if you want, but a small one in the screw hole won't add that much time.

I used PLA at 20% infill and it worked just fine.

Bracket should slide easily along extrusion bar and stay snug.

Please let me know if you have issues!
