I bought my son an Ender 3 for his birthday and unfortunately he had a few problems due to the cheap parts that came with it - The Material Feeder was der The first problem we encountered 48 hours after using it. The son turned the prints over and barely gave the printer a break when he suddenly stopped feeding. I couldn't figure out why, read many articles and watched YouTube troubleshooting videos, but none of the solutions helped. In the end I decided to just take the feeder apart to see if I could see anything - and here it is! The lower plastic was torn, preventing the upper pulley from moving freely. I ordered this component and it turned out to be the perfect solution. It was fairly easy to put together - probably 15 minutes, and if you're careful how you removed the old feeder then this feeder assembles the same way. However, there are no instructions here, only an exploded view, which is only of limited use as an installation reference. After replacing this component worked perfectly - wow! For the $12.86 this part cost, it's absurd that Crealty wouldn't include it in their printers. At $12.86 with free shipping, Crealty should cost $2 or $3 to make.
