As the title said, I'm looking for an arm sling, but I need the old style one, like this

Has anyone seen one?

I could probably make one for you if it's for a figure I own. It would be a simple static prop suitable for one pose, I don't have time to get involved in option morphs  and so on.

I'm needing it for m3 but if it's just a prop, If it fit any of the guys, I could just use the morph brush to help it fit him.

Unfortunately I don't have M3. It'll need to fit quite well to look believable - it needs to pull tight around the neck and under the arm so it looks like it is taking the weight of the arm, and the tension creases need to be long and straight or they'll look fake. I think you'd have quite a job morphing it from one figure to another with the morph brush, probably easier to make it directly on your posed figure in wings or something.

Make the bit around the back of the neck, make the bit under the arm, bridge between them to make the front panel, copy the top of that to make the part against the chest, tweak a bit, done.

You have more confidence in my modeling skills than I do. Thanks for the offer.

I managed to get something I only had to take it into 3 programs to get it done. It's not fabulous, but it'll work for what I have in mind. The points on the bottom won't show. Some day, I'm gonna have to learn to model.

There ya go! Well done, now you have a sling AND some more modelling experience under your belt, priceless. That experience will go directly into your next project, and the next, and pretty soon you'll have dozens, perhaps even hundreds, of unfinished models on you hard drive, just like the rest of us. It's a curse, I tell you, this modelling thing.
