aw man.... another critical joint..

u can try supaglue or cement it, but not sure if the strain induced by movement will break it again

I wonder if my technique with repairing Freedom backpack could be used.

I drilled both parts and insert something (toothpick for my case, but I prefer you use needle) then use best superglue you could have





the joint won't suffer any articulation lost if you set it right

cement/super glue should work or get spare part from bootleg kit

yeah, in my case I drill both part with pinvise 0.1mm
if you can't find any brass rod (I don't know where to look), just find yourself a small-diameter needle, I think it might work, and be carefull of your finger.

I use toothpick 



and yeah... it's frail, not recommended
