If you have a tripod or light stand that has the big-old 3/8" screw on it, and you want to put something that takes the more normal ¼" 20, then this is what you need.

Print this with your most robust filament with the best layer adhesion. I used PETG, and it is very strong. My profile is set up for strength.

That's it, really. I cannot think of much more to say.

As always, I would appreciate a ‘like’ if you find this helpful, and see if you could rate the profile as well. It doesn't cost anything but makes this big old fella happy.

Oh, and don't tell me that I could unscrew that thing on top of my tripod: I know that. It was just handy for the photos. 😀
