i've printed the peg springs version first and it was awful

the spring was blocking the mechanism making impossible to make the blade go all the way up resulting in a bit of the blade peeking on the holes from his resting position, when i've tried to slide the PTFE tube in his slot a bit of it got scratched, maybe the spring wasn't the wright one but having the spring not centered just sucks no matter the sanding,
and it was nearly impossible to get a straight cut

then i've printed the other version featured in the photos of the assembly and since i didn't had the requested spring i had to make one myself by wrapping around a 1mm steel wire around a 3.2 diameter steel rod and IT WORKED!
cuts well and straight, the machanism works as it's supposed to

in order to not waste material i've mounted on the bad ''peg springs'' version the open blade variant

@Sazelot_434676 The same happened to me with peg spring version. Waste!
