These are great! Do you mind if I ask a question about them?
I'm making a prop at the minute, but because of the size of it I need to be able to make it detachable. I'd already planned the method out when I stumbled across this, but do you mind me asking what you used for the prop in the bottom left corner?
Did you manage to find a pole that was already like that (if so, do they have a specific name), or did you have to put the screws in yourself?
