The button used for the folding brace seems to constantly fail on the same lip of the button retainer. To remedy this, I have added 2 channels for 6-10mm long M3 grub screws(choose a size based on how much you want sticking out the top). Applying a little heat to the grub screw makes screwing in the channels easier without cracking plastic.
