CR-10 Spring Tensioner

thingiverse

I had a lot of issues with the extruder slipping and prints failing due to the stock CR-10 spring being weak with next to no tension and next to no way to adjust it. I came up with this spacer/spring holder to increase tension. It works well a little too well as you have to have pretty strong hands to open the clamp after putting it on. I have not had any slipping after it was on and it does not grind into the filament. Hope this helps. Note this is in gcode due to fusion360 not letting me export as a stl. Copy to sd card and print from main box or rescale the z axis to 10mm if you're using simplify 3d.
