Ender 3 extruder feeder assembly spring tension fix

thingiverse

A small shim to place over the lug that holds the spring in place on the extruder feeder assembly, to increase tension in the spring and prevent underextrusion. Similar designs to the others on here, only when I printed them the hole was too small to go over the lug that holds the spring (maybe there was a redesign at some point?) these can be mounted either on the extruder feeder assembly arm, the plate or both. included are 0.5mm 1mm 1.5mm 2mm NOTE: After installing these, do not over tighten the bolt that holds the arm in place, it needs to be loose to work properly. If the arm squeaks when you move it or if you can feel the arm dragging on the bottom plate it's too tight, the only resistance you should get is from the spring.
