Ergodox tent kit with Rev-8 board breaks off transistor

[ptdewey]

I printed both the ergodox 1.5mm middle layer and the tenting legs and adapters, and after installing them with M3 16mm screws, I noticed that the 6 key stopped working. Upon further investigation I found that the screw broke off the transistor for that key by pushing through it.
I followed the official iris assembly guide and the pdf in the ergodox tent legs folder.

I think adding an extra nut in the inside of the leg before the screw would reduce the amount the screw juts our of the middle layer hole, but I'm not completely certain.

This also only happened on the right board because the transistor for the keyslot on the left board is located lower on the pcb.

There also appears to be some scratching of the PCBs in the other places where the screws come through also, but it seems more extreme on the right board for some reason.
