Design Ideas

Hey! I need some help with a mechanism for a project.

I’m trying to design arms that lift up from inside a tube/cylinder, open outward, and then close back down again. Kind of similar to how an umbrella opens, but it doesn’t have to work exactly like that.

I’ve already 3D printed one attempt, but I’m struggling to figure out a clean mechanism that can actually be printed and assembled properly. I’m using Fusion 360 and the whole thing needs to be suitable for 3D printing.

I don’t really mind HOW the opening system works — springs, sliders, hinges, telescopic parts, etc. I just need a way to make it look cohesive and functional when fully assembled. (The blue in the photo is cloth btw)

Does anyone know of mechanisms, references, tutorials, or products I should look into? Even rough sketches or keywords would help heaps. Thanks!
