I'm modeling this gun/sword
I need to learn how to make a mechanism that works like this
Push to rotate
The center of that cylinder is already being used to fuse the front and back of the cylinder. So, the mechanism can't go through there

Hey @clear oxide, thank you for contributing to this forum.
Please provide as much information (images, video, description) as you can. This will increase the chance that someone can help you with your issue.
Use the Close button when your issue is resolved.

What cylinder are you referring to when you are saying you using it to fuse the front and back?
clear oxide
Let me show you
The pieces are separated like that
Without the front and back pieces look like this
And they are fit together inside of that hole of the middle piece
They fit together with snap fit joints, for them to rotate at the same time
The problem is, I need a mechanism to release this pieces and allow them to rotate when the button is pushed like in the video

In the original design whatever they use as a mechanism is contained within that area and if you want it to be the same thing like the original your current design for the two cap like pieces may not work to be able to make a functioning mechanism
But I may have an idea for a mechanism that will possibly function just like the toy but it completely changes your idea if you are open to it.

You want it to lock in both positions?

so this would lock the hinge in two positions. the pushbutton needs to be spring loaded. i didnt go through the steps of making for assembly, but im sure you can figure that part out yourself
the hinged part has a key on it that fits into a keyway on the pushbutton. when the pushbutton is pressed in, the key slides into a channel on the pushbutton that allows it to rotate freely 90 degrees
at the end of the channel is another keyway that the key will slide into. the compression of the spring will reset the pushbutton and lock the key into the second keyway. same thing in the other direction to close the hinge
If you wanted the hinge to move in one direction without the use of a pushbutton (i.e. button is pressed to open hinge, but hinge can be closed just by rotating it without manually using the pushbutton), you can cut a chamfer into one of the keyways that allows the key to cam the pushbutton open on its own
as far as using the original design goes: when im recreating something like this, i toss out any mechanisms that dont lend themselves to 3d printing. i try to do whatever requires the least extra hardware and is the most durable. injection-molded parts have a much easier time, so i often replace mechanisms with my own
ofc this is far from the only way to do it. just what immediately came to mind

Similar to my idea @sullen tendon but I would do 2 stopping points and the neyway to remove the button. One to stop it in sword mode, one stop in gun, and the keyway to an edge to remove the button. Then it will have a spring. I'm gonna make a mockup to show it better shortly
The way to remove the button would be rotating the hilt another 90 degrees past gun mode and then the key will follow the keyway to the edge of the button cylinder

Yes, I wan't to lock on both positions

Alright
