A1: The magic screw no-one talks about

Hi there,

it’s not important, but I’m curious. There is one screw at the print head of the A1 with a triangle head (not triwing). Normally, this is used for security reasons. But no-one found out, what it’s for. I found 2 Reddit-Threads about it but with no conclusion. Would be great to learn about it.

the fact that there is a spring behind it narrows down its function but even without knowing what its for it’d mean its removal would probably be a d*ck and a half to put back on if messed around with.
