Selfie stick part

One part of the selfie stick is broken, so I plan to replace it.
The thread of the screw is not metric, so I used the original one. It may not match yours.
The parts fit very tightly to hold the bolt firmly against displacement. I fixed the crease in place using a washer.
I also used a little glue for an even stronger hold.

Update:
I reduced the height of the main element by 2 mm so that it could turn in the slot under the phone holder.
