Spring Replacement Ender 3

thingiverse

After under-extrusion appeared, I noticed that the spring no longer tightens properly. I temporarily printed out the part until a replacement was found, but it's been in for two months now and I thought I'd just share it. You don't have to remove the old spring; it fits over the existing one. It's practical if you change filament, then you can pull it off and still have a spring that tightens at least a bit. -------- After under-extrusion made itself known, I realized that the spring was no longer tightening properly.
