FlashForge Creater Pro - Spring loaded extruder block

Emm... spring loaded............

I just happened to love printed spring, so I made this just to see if it works or not.

printed in PLA, but ABS should have a better temperature resistance.

the tension is slightly adjustable, just insert some paper between the spring and the holder.
I'm trying to see if I can make it adjustable by some screw and bolt, but that might take some time.
