this is a spring to stabilise the x axis on a printrbot lc
my x axis on my Printrbot lc was wiggling during violent direction changes, so I made this spring to sure it up a bit
Best printed using a fan from the 6th layer onwards but can be successfully printed without if your desperate.
My print quality has definitely improved since adding this and i hope yours does too
try printing two (one for each side)
IMPORTANT print at 1.2 scale as I'm still learning to get the scaling right but 1.2 works fine
