Wanhao i3 Adjustable Tension Extruder Lever

I added an adjustable spring perch to increase tension to the extruder lever. My extruder spring was getting a bit weak and causing extruder skipping which this solved for me.

Fasteners required:
3mm nut
3mm x 20mm cap or socket screw
3mm x 10mm flat head screw (holds the v-groove bearing)
