7:16 This is why I hate the risk of moving joints breaking carelessly with too much force. The only safest way is " to push softly with a thumb (or wiggle left and right to rotate) until it stops the braking point " Going beyond braking point will stress the plastic further so be careful not to go way too far and hard. It reminds me of a plastic material of a base stand's connector which is very durable but breakable if bend too much. A superglue might be ideal at least held 2-Tons will do the fixing trick.
